Q1. Equilibrium of a particle
Calculate TCA and TCB.
Q2. The jib crane is oriented so that the boom DA is parallel to the x axis. At the instant shown, the tension in cable AB is 13 kN. Determine the moment about each of the coordinate axes of the force exerted on A by the cable AB.
Determine also the moment about the axis DA.
Q3. Determine the horizontal and vertical components of reaction at the pin A and the tension developed in cable BC used to support the steel frame.
Q4. Determine the normal force, shear force, and moment at point C.
Q5. Two solid cylindrical rods are joined at B and loaded as shown. Rod AB is made of steel (E = 29 x 106 psi), and rod BC of brass (E = 15 x 106 psi). Determine (a) the total deformation of the composite road ABC, (b) the deflection of point B.
