Please do it ASAP and correct The official record for the largest diameter loop-the-loop in a car is currently 19.49 m (see Figure 2). A driver attempts a new record with a loop diameter of 24 m.(a) What is the minimum velocity at the top of the loop in km/h to ensure the loop can be completed without the car falling?Answer: velocity =km/h. Give answer to 3 or 4 significant figures.(b) What is the maximum velocity of the car in km/h at the entry to the loop to ensure that the centripetal acceleration experienced by the driver does not exceed 5.7g, where gis the accelerationdue to gravity?Answer: velocity =km/h. Give answer to 3 or 4 significant figures.(C) If the mass of the car is 1531 kg, what is the normal force in kN experienced by the car on entry to the loop if the centripetal acceleration is 5.7g?Answer: Normal force =kN. Give answer to 3 or 4 significant figures.

A. A motorcycle and rider have a combined mass of 350kg. The wheels each have a mass of 20kg, diameter of 500mm and radius of gyration of 200mm. The rider accelerates uniformly from 5m/s to 25m/s over a distance of 100m, whilst climbing a hill of slope 1 in 20. The average resistance to motion, including drag, is 105 N. 1. Determine the total work done as the motorcycle ascends the incline. 2. Calculate the amount of power developed during the climb. B. At another point in its journey, the motorcycle and rider travel at 80 km/h around a left-hand bend of radius 30m. Calculate: 1. The angular velocity of each of the wheels. 2. The moment of inertia of each wheel. 3. The magnitude and effect of the gyroscopic torque produced on the bike.
Pipelines are cleaned by pushing through them a closefitting cylinder called a pig . The name comes from thesquealing noise it makes sliding along. Reference 50describes a new nontoxic pig, driven by compressed air, forcleaning cosmetic and beverage pipes. Suppose the pigdiameter is 5-15/16 in and its length 26 in. It cleans a6-in-diameter pipe at a speed of 1.2 m/s. If the clearance isfi lled with glycerin at 20 8 C, what pressure difference, inpascals, is needed to drive the pig? Assume a linear velocityprofi le in the oil and neglect air drag.
Dynamics of Rigid Bodies Problem: 1.) A diver jumps from a height of 3.0 metres above the height of the water and touches the surface 1.0 s later. What was his velocity when he hit the water? 2.) A motorcyclist, travelling at a speed of 30 m/s, sees an obstacle 100 metres in front of him and puts on the brakes. He hits it 5.0 seconds later. If the motorcycle slows down uniformly, how fast was it going at the instant of the collision?
Suppose you are designing the propeller of a radio-controlled model airplane. The overall diameter of the propeller is 34.0 cm, and the hub assembly diameter is 5.5 cm. The propeller rotates at 1700 rpm, and the airfoil chosen for the propeller cross section achieves its maximum efficiency at an angle of attack of 14°. When the airplane flies at 30 mi/h (13.4 m/s), calculate the blade pitch angle from the root to the tip of the blade such that ? = 14° everywhere along the propeller blade.
Given: lambda = 10 m, mass of the vehicle, m= 1000kg, k=9000 N/m, speed 60/2pi m/s. Interpret this graph for me. What happens if we go to the right? What happens if we go to the left? If we want to have a great magnitude of vibrations according to the graph should we increase or decrease our speed? explain. What if b is decreasing but we maintain our speed would b decrease or increase the magnitude? Why? If we are driving at the speed that always maximizes the magnitude of the shaking will decreasing b increase or decrease magnitude?
please answer A pump impeller rotating at 1400 rpm has an outside radius of 21 cm, the vane outlet angle β2 is 158° and the radial velocity at the outlet Cr2 is 4 m/s. Assuming radial flow at inlet, draw the theoretical outlet velocity diagram and calculate the various velocities and angles.( A)What is the theoretical head Ho, in meters, assuming that the circulatory flow coefficient η∞ = 1.,(B)In the preceding example; assume a deviation of 10° applied to β2 due to circulation after the modern theory. The flow is 30 lit/s. After drawing/illustrating the velocity diagram, find the theoretical head Ho, in meters, assuming radial flow at inlet, neglecting the deviation in inlet velocity diagram. (c)Assuming that the mechanical efficiency ηmech = 0.95, the hydraulic (or manometric) efficiency ηman = 0.8, find the required break horsepower to drive the pump.
When rowing downstream consider the following scenario. The current of the water is moving at 2 m/s in the direction you are rowing. The coefficient of drag between your boat and the water is 1.2, the area in contact with the water is 0.1 m2 and the density of the water is 1000 kg/m3. You are moving at a velocity of 4 m/s into a head wind of 4 m/s. Your coefficient of drag between you and the air is 1.4, the area in contact with the air is 0.4 m2 and the density of the air is 1.2 kg/m3. Your goal is to create a net force moving downstream that is equal to 100 N. How much force must you exert with the oar and in what direction to achieve this net force downstream?
A windmill turns a series of slender rods fixed about one end . They are initially 2 meters long, and go at a speed of 15 revolutions per minute. I suggested making the blades 1m long to reduce the cross-sectional area of the windmill, keeping the mass the same for mechanical stress consistency. How fast are the windmill blades going now, in revolutions per minute?
Example 9.15 A rope, to which a weight is attached, passes around a pulley 50 cm in diameter. The angular acceleration of the pulley is 18 rad/s2. If the pulley is initially rest, find a- The time required for the weight to attain a velocity of 15 m/s b- The number of revolution through which the pulley rotates during that period, c- The total acceleration of a point on the rim of the pulley 0.5 second after it was at rest.
A multi-rotor propeller has a geometric pitch angle of 9 degrees at a point 0.11 m from the shaft. If the inflow velocity at this point is 3 m/s and the propeller is spinning at 2,000 RPM, what is the local angle of attack?
A disk rotating with constant acceleration of 0.005 revolutions / s2 And the movement starts from rest. What is the angle velocity after one minute? How many turns makes the same disc in point number one after one minute. If an external force does not affect the body, what does that mean? And if the body is in free fall, is its speed constant or variable, what is its acceleration equal, and how can the friction be reduced between the contact surfaces
