A belt moves between the pulleys of the crankshaft of the air conditioning fan and over the idler pulleys in the section shown in the figure during an interval of 7 seconds, uniformly increasing its speed from Vo = 3 ft/s to vf = 7ft/s., knowing nailing 1 slide on the pulleys Determine a) the angular acceleration of the pulley b) the number of revolutions made by the pulley during the interval of acceleration alternator A = 4.5 in crankshaft A direction

At the instant wA=4 rad/s, pulley A is given an angulan (0.70) rad/s, where 0 is in radians. acceleration a= Pulley C has an inner hub which is fixed to its outer one and turns with it. (Figure 1) Y Part A Determine the magnitude of acceleration of point B on pulley C when A rotates 3 revolutions. Express your answer to three significant figures and include the appropriate units.

An electric motor has a rotor with a mass moment of inertia of 22 ft-lb-s2. What torque is required to accelerate it from rest to 1,174 rpm in 3.6 seconds? Provide your answer in lb-ft and round to the nearest whole number. An electric motor has a rotor with a mass moment of inertia of 22 ft-lb-s2.
