A bowling ball which is held by a mouse using a rope, accidentally fall down a floor slab as shown in Figure 1b. The mass of the ball is 1.5kg. Draw the free body diagram and force triangle of the equilibrium system. Determine the magnitude and direction of the smallest tension P in the rope to maintain the ball at its current position. Calculate the corresponding reaction force by the surface of the slab.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
