Abbot and Costello are transporting a 0.125m3cubic block along a ramp inclined at 20°. They tied the block under the midpoint of a 3m, 2kg, pole-arm. Abbot is at the lower end of the pole while Costello leads the pair up, holding the other end of the pole. Calculate the upward forces exerted by Abbot and Costello during the transport if the block weighs 1000N.
Jeffery is cleaning up around the house. He moves a box with a mass of 55.0kg onto the garage table that is 4.00m long. The legs of the table are both located 0.200m from each end and the box is placed 1.40m from the left end of the table. If the tabletop has a mass of 235kg, what are the forces due to each of the legs on the table, in Newtons? Let FA be the force from the table leg on the left side and FB be the force from the table leg on the right side.
