A sign for a pizza restaurant hangs from a 2.60-m long rod extended out from a building. A cable, attached to the building, is attached to the rod at a point that is 2.10 m from the hidge. (See the figure.) The mass of the rod is 3.20 kg. The mass of the sign is 7.10 kg. The angle between the building and the rod is 69.0 degrees. The angle between the cable and the horizontal is 36.0 degrees. The tension in the cable is 117.5 N. What is the vertical component of the reaction force from then hinge on the rod?

When rebuilding his car's engine, a mechanic must exert 300'N of force to insert a dry steel piston into a steel cylinder. What is the magnitude of the normal force between the piston and cylinder? (b) What is the magnitude of the force would he have to exert if the steel parts were oiled? (us for dry steel on steel = 0.6; µk for dry steel on steel = 0.3; us for oiled steel on steel = 0.05; µk for oiled steel on steel = 0.03)

Two builders carry a sheet of drywall up a ramp. Assume that W = 1.9 m, L = 3.3 m, theta = 19.0⁰, and that the lead builder carries a weight of 109.0 N (24.5 lb). L- Ө What is the weight carried by the builder at the rear? HINT: Consider the drywall to have no thickness. The builder at the rear gets tired and suggests that the drywall should be held by its narrow side. ~W~ 0 What is the weight he must now carry? HINT: From the previous problem, you know how much each builder carries. Therefore you know the total weight. Set the sum of the torques about the front lower corner to 0, so that you do not need to know the weight carried by the builder in front.
