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.
Three identical steel balls, each of mass m=85kg, are placed in the cylindrical ring which rests on a horizontal surface and whose height is slightly greater than the radius of the balls. The diameter of the ring is such that the balls are virtually touching one another. A fourth identical ball is then placed on top of the three balls. Determine the force P (in N, roundoff to 2 decimal places exerted by the ring on each of the three lower balls.
