EXAMPLE 52 Two-dimensional equilibrium Now we will look at an example where several forces are acting on an object, but in this case the forces are not all along the same axis, As shown in Figure 5.2a, a car engine with weight w hangs from a chain that is linked at point o to two other chains, one fastened to the ceiling and the other to the wall. Find the tension in each of the three chains, assuming that w...

The beam ABC has a mass of 78.0 kg and is supported by the rope BDC that runs through the frictionless pulley at D. The winch at CC has a mass of 44.5 kg. The tension in the rope acts on the beam at points B and C and counteracts the moments due to the beam's weight (acting vertically at the midpoint of its length) and the weight of the winch (acting vertically at point C) such that the resultant...
Shear and Bending Moment Diagrams Learning Goal: To determine the reactive forces and moments acting on a beam; express the shear and bending moment as functions of their positions along the beam; and construct shear and bending moment diagrams. The cantilever beam shown is subjected to a moment at A and a distributed load that acts over segment BC, and is fixed at C. Determine the reactions at the support located at C. Then write expressions for shear and bending...
