1.The table lamp consists of two uniform arms, each weighing 0.8 lb, and a 2-lb bulb fixture. If ? = 16? , calculate the couple C A that must be supplied by the friction in joint A.

2.A truck is traveling down a road with a 3-percent grade at a speed of 55 mi/h when the brakes are applied. Knowing the coefficients of friction between the load and the flatbed trailer shown (us= 0.40) and (uk= 0.35), determine the shortest time in which the rig can be brought to a stop if the load is not to shift.
