QUESTION 2 The crate is being lifted up the inclined plane using the motor M and the rope and pulley arrangement shown. Determine the speed at which the cable must be taken up by the motor in order to move the crate up the plane with a constant speed of 85.17 m/sec.
The cylinder rotates about the fixed z-axis in the direction indicated. If the speed of point A is VA = 2.7 ft/sec and the magnitude of its acceleration is a A = 29.6 ft/sec?, determine the magnitudes of the angular velocity and angular acceleration of the cylinder. Is knowledge of the angle e necessary? Part 1 Determine the magnitude of the angular velocity of the cylinder. Answer: w = rad/sec
The 380-lb cylinder at A is hoisted using the motor and the
pulley system shown. The speed of point B on the cable is increased
at a constant rate from zero to vB = 10 ft/s in t = 5 s
Determine the tension in the cable at B to cause the motion.
You drop a lead cylinder with a radius of 0.500 cm and a length of 2.50 cm into a tank of water. The density of lead is 11,342 kg/m . As the cylinder sinks towards the bottom, it moves at a constant speed. (a) What is the weight of the cylinder? (b) What is the magnitude of the resistive force exerted on the cylinder as it moves through the fluid?
The cylinder rotates about the fixed z-axis in the
direction indicated. If the speed of point A is
vA = 3.3 ft/sec and the magnitude of its
acceleration is aA = 50.6 ft/sec2,

A heavy solid cylinder with a mass of 600 kg and a radius of 0.50 m is securely fixed to a frictionless axle at its center. It has a long ideal rope tightly wound around it and hanging down from the cylinder about 1.0 m. Sally, who has a mass of 60 kg attaches herself to the rope and steps off a ledge, spinning the cylinder about the axle. If it takes 4.0 seconds for her to reach the ground...
As a hydraulic cylinder rotates around O, the exposed length L of the piston rod P is controlled by the action of oil pressure in the cylinder. If the cylinder rotates at a constant rate 0- 60 deg/sec and L is decreasing at the constant rate of 150 mm/sec, calculate the magnitudes of the velocity and acceleration A of end B when L-125mm V 375 m 1)
