Essay on Modelling a Frame Subjected to Multiple Loading Conditions

The specimen ends were not thick or had moving wedge grips to keep it secure in the holders of the servo-hydraulic load frame. The movement of the specimen in the machine causes some of the data to be an inaccuracy. Also, the transverse strain causes issues with the strain gages that are called transverse sensitivity. The transverse sensitivity affects the accuracy of the data that is being collected for the transverse strain more than the longitudinal strain. This is greatly seen in the percent difference in the strain values such as in one case the Longitudinal strain was .4% while the transverse strain was 30%. Another issue with the strain gages was that if the strain gages weren’t properly placed on the specimen the data accuracy would

2. Using the protractor, measure the angle of the ramp making sure the angle of the ramp is 10˚.

First, we will set up the force table. The table comes in three separate pieces the base, stand and table once we connect and fasten all three parts we must use a circular level to make sure the table is balanced. If the force table isn’t balanced then we must adjust the base’s feet to the appropriate levels on each leg till the bubble on the level is centered. We must then assign where the positive & negative x, y axis are on the force table as a point of reference and label them with tape .Then for part I we must apply 1.96 N in the positive x – direction, and 2.94 N in the positive y-direction then we must balance the two with a third force and record the magnitude and direction of it and a draw a diagram showing all three forces. Part II

Average accuracy of the above meter. Solution: Compute the Kh of the standard used For Light Load : Kh = 0.6 X 240 = 1.2 120 For Full Load : Kh = 0.6 X 240 X 50 = 12 120 5 a) Compute the Light Load rev. based on the meter and standard CR = Kh(MUT) X Rev.(MUT) X V(std)  = 28.8 X 1 = 24 Kh(std) X No. of Element X V(MUT)

There are several secrets and techniques to hardcore frame building also called the working ideas of this type of sport; athletes encompass right here weight loss program, sleep and workout recurring as the primary elements, followed by means of commitment, right hydration and avoidance of over training.

Purpose: -To understand Boyle’s and Charles’ theory. -To explain the relationship between temperature, and pressure of a gas. - To explain how the pressure in a container of gas is affected when the volume is changed.

This report aims to describe the experiment performed to investigate the stiffness of a channel section, and in particular calculate the flexural rigidity (EI) of the beam by two different sets of calculations based on the results gained in the experiment. The EI of an object is used

First, connect Logger Force Probe to the computer before starting up the computer. Follow the connection by connecting motion detector sonic/DIG 2”, and then connect “ch 1” to the force sensor. Set the force sensor to 10N on the scale. Determine the masses of equipment you want to use and force sensor. Go to your computer desktop and click on the LoggerPro Software icon. On the opened LogggerPro Software, click on the oval icon (possess LabProbe Insode). Set ch1 to ‘Force Sensor, Pasco, 10N’ by clicking on ch1. Calibrate the sensor force by clicking on the calibrate tab while handing nothing on the sensor hook and then key in zero (0). Hang approximately 250 grams (the mass of the hanger and another mass (about 200 grams));

A smart pulley is clamped onto the side of the table and connected to a computer to sync with Capstone. In Capstone, select the device as “Photogate with Pulley.” Set up a position vs time graph to record data for. Attach a string to the cart, over the smart pulley, and latch it onto a 5g hook to the side of the table. Obtain four weights: two 20g, one 50g, and one 100g. While keeping the cart in place, keep one 20g weight on the hook and the remainder in the cart. Start recording data from the smart pulley and release the cart so that it will slowly slide towards the edge of the table. Grab the cart before it hits the pulley and stop recording data. Reset the cart's position to 50 cm away from the edge. Repeat this process for the following masses on the hook: 40g (two 20g weights), 70g (one 20g weight and a 50g weight), 100g (just the 100g weight), and 170g (one 20g, 50g, and 100g). Keep the remainder weights on the cart. Be careful with the cart at higher masses on the hook, as it will move quickly. Once the trials are completed, create quadratic fits for the recorded data on Capstone. Make sure to remove unwanted data, such as the initial motionless state of the cart and the adrupt halt of its motion. The acceleration of the system is two times the value of the A constant in the curve fit; record this and do this for all trials.

We used a rig which consisted of a beam which is symmetrically and simply supported on each side. The 5 strain gauges were an

Below are two tables in which I have recorded the data which I obtained during the experiment. The first table reflects the Relationship between the deflection/flexion of the cantilever and the mass of the load and the second table reflects the relationship between the flexion of the cantilever and the length of the cantilever.

Table 1 & 2: First, find the mass of the wooden block and record the data. Then place the wooden block on the inclined plane (at 0o) with the wide side down. The height of the pulley should be the same height as the screw location on the wooden block. Then hang a weight on the opposite side of the hanger and add weights until block starts to move with a constant velocity (push block to overcome fs¬). Then record the resulted weight of the hanger in Table 1 (as F). Add 500 g to the wooden block and repeat the process. Replace 500 g with 1 kg on the wooden block. Repeat the process described above.

The Computer and sensor calibration along with equipment such as DIN plug, force sensor, rod, clamp, spring, sensor’s hook, and hanger were all set up already in the laboratory before we started doing the experiment.

In another study, Erochko et al. [3] examined the residual drift response of special moment-resisting frames (SMRFs) and buckling-restrained braced frames (BRBFs). It was found that both types of building systems experience significant residual drifts, with values between 0.8-1.5% for the SMRFs and 0.8-2.0% for the BRBFs under design-based excitations. By reducing residual drifts of a structure subjected to a seismic event, structural engineers can maximize post-event functionality, reduce the cost to repair the structures, and increase the public safety.

Problem 111 For the truss shown in Fig. P-111, calculate the stresses in members CE, DE, and DF. The crosssectional area of each member is 1.8 in2. Indicate tension (T) or compression (C).
