I). Equilibrium of 3-D Rigid Body
The plate weighs 350 N. Determine the force in each cable (TA TB Tc) if it is suspended in the horizontal plane.
2). Method of Section
Determine the force in members GE, GC, and BC of the truss shown. Indicate whether the members are in tension or compression.
3). Shear and Moment Diagram
a). Construct a shear diagram for the beam shown below. b). Construct a bending moment diagram for the beam shown below.
4). Friction
a). Determine the minimal horizontal force P that will prevent the 1750-lb crate from slipping down the inclined plane. Usc µs = 0.3
b). Determine the minimal horizontal force P will push the 500-lb crate up the inclined plane. Use vs = 0.2
5). Moment of Inertia
Determine the moment of inertia (Ix) of the cross section of I-beam shown, with respect to the x axis.
