The rope that is wound around a drum wheel lifts the bucket, as shown in the figure. If the angular displacement of the wheel is given by the expression 0 = (0.5t³ + 4t) rad, where t is in seconds, determine the acceleration of the bucket (in ft/s²) when t = 3.0 s.

The design of a camshaft-drive system of a four-cylinder automobile engine is shown. As the engine is revved up, the belt speed v changes uniformly from 3.9 m/s to 5.2 m/s over a 2.6-second interval. Calculate the magnitudes of the accelerations of points P₁ and P2 halfway through this time interval. Your answer is partially correct.

The motor turns gear A with a constant angular acceleration, a = 4 rad/s², starting from rest. TA=71, rB=230, rp=121 The cord is wrapped around pulley D which is rigidly attached to gear B. LA TA rB "D з тав Find the distance of cylinder C in mm that it travels it t=2.4 sec. Give your answer as an integer.

The design of a camshaft drive system of a four-cylinder automobile engine is shown. As the engine is revved-up, the belt speed v changes uniformly from 8 m/s to 22 m/s over 2.5 seconds. Calculate the magnitudes of the accelerations of points P₁ and P₂ at the end of the time interval. Camshaft sprocket Drive belt tensioner Crankshaft sprocket 60 mm Intermediate sprocket
