A submarine is 285 m horizontally from the shore of a freshwater lake and 111 m beneath the surface of the water. A laser beam is sent from the submarine so that the beam strikes the surface of the water 201 m from the shore. A building stands on the shore, and the laser beam hits a target at the top of the building. The goal is to find the height of the target above sea level. Find the angle of incidence of the beam striking the water-air interface.

1. A non-uniform is 4.5m long and weighs 640N. It is balance when a 270N weight is hung 0.800m from the light end of the bar and the bar is pivoted at its center. Where is the center of gravity of the bar? 2.Two workers carry a non-uniform beam weighing 730N. The beam is 2.6m long and its center of gravity is 1.1 m from one end. If the workers hold the beam at its end, how much does each worker lift?
A 11120 N car is designed with a 310 cm wheelbase. The center of gravity is located 60 cm above the pavement and 105 cm behind the front axle. If the coefficient of road adhesion is 0.6, what is the maximum tractive effort that can be developed if the car is (a) front-wheel drive and (b) rear-wheel drive? (c) how far back from the front axle would the center of gravity have to be to ensure that the maximum tractive effort developed for front- and rear-wheel drive options is equal?
According to the Department of Transportation analysis of energy consumption figures for 1974 and 1975, observation of daylight saving time in the month of April in the years of 1974 and 1975 saved the country an estimated energy equivalent of 10,000 barrels of oil each day. Estimate how much energy is saved in the United States or your country due to observing daylight saving time in the current year.
One of your employees is complaining of knee pain on the R. While assessing his workstation, you noted that from a sitting position (starting position: 90 deg flexion), the employee needs to exert a lot of effort to extend his right knee to 45 deg from the starting point. The length of the limb (from the tibial tuberosity to the heel area) is measured to be 38 cm. What now is the linear distance traveled by the limb from the initial position to 45 degrees of knee extension?
During a bicep curl on a bicep curl machine, I'm curling a weight stack of 100 pounds (single arm...I'm jacked like that). At this very moment, the weight stack has a moment arm of 0.12m, my elbow has an angle of 63deg, my muscle force vector has an angle of 23deg, and it attaches 3cm below my elbow joint on my radius. How much force must my bicep create right at this moment to hold the weight stack in place?
Use Hottel's Crossed String Method to find Fij. The distance between the plane and the circle is 25cm, with radius at 6cm. Also, the circle is at the left of the plane, where it has the same center line as the plane.

In the United States, energy for household heating is generally sold using English units, e.g., therm, gal, and cord. A house in Wisconsin uses 1200 therms of thermal energy during the heating season. Calculate the cost of fuel if the furnace uses (a) natural gas with an efficiency of 70%; (b) No. 2 fuel oil, efficiency 65%; (c) kerosene, efficiency 99.9% (unvented); and (d) wood with l5% moisture with an efficiency of 50%. Use the data in Tables 2.2, 2.7, and 2.13. The efficiencies are based on the HHV. Assume the cost of natural gas is $8/MBtu, the cost of No. 2 fuel oil is $3/gal, the cost of kerosene is $3.50/gal, and the cost of wood is $100/cord. Assume the bulk density of cord wood is 30 lbm/ft3 .
01: A 105cm Rod is suspended on a wall with a 5N force pulling upwards, 110 degrees away from the horizontal axis and 5cm from a 50kgm hanging object. Find the location of the C.G. away from the wall. Neglect the Mass of the rod and consider it a rigid body. Assume SSLC. 02: Considering a CCW movement is Positive, what is the total value of the Negative Moments at the point with the 50kgm object? Please answer in four decimal places, in Nm. 03: What is the value of C.G. away from the wall? (in meters, two decimal places)
A horizontal wind turbine has been installed near the sea shore. (a) Estimate the mechanical power generation of this turbine using the fundamental equation of wind power. (b) Consider that in the morning the temperature of the turbine installation place is 20 °C, and air has a density of approximately 1.204 kg/m3. However, at noon, the temperature of the place is increased to 34°C. Then, estimate the change in mechanical power output of the wind turbine. (Consider all other parameters remain constant). (c)Calculate the highest possible electricity generation by this wind turbine at noon time. (d)If the installed wind turbine's turbine cost is RM450,000 which the rated power is 600 kW and the capacity factor is 28.54%, estimate the possible leve/ised cost of electricity for 30 years of operation .
