The scissors lift consists of two sets of symmetrically placed cross members (one in front that is shown and one behind that is not shown) and two hydraulic cylinders (front [labeled DE] and back [not shown]). The uniform platform has a mass of 60 kg with a center of gravity at G1. The 85 kg load (center of gravity at G2) is centered front to back. Determine the force in each of the hydraulic cylinders necessary to maintain equilibrium. These are rollers at B and D.
Determine the horizontal and vertical components of force at pins A and C of the two-member frame.
A horizontal semi-circular beam of radius ‘R’ is fixed at the ends and carries a uniformly distributed load ‘W’ over the entire length. The bending moment at the fixed support is
