(a)

(b)

(c)

Estimate the magnitude and direction of the angular velocity of the output link. Show your

reasoning.

Estimate the mechanical advantage at the instant shown. Show your reasoning.

A constant load torque of 50 N-m CCW is applied to the output link. Estimate the

magnitude of the torque that the driving motor must supply to the input link at the instant

shown. Show your reasoning.

(d) Draw a vector at P showing the direction of the absolute velocity of point P. Show your

reasoning. (You are not required to find the magnitude of the velocity of point P.)
