Assignment:
Problems:
1. No FBD required.
a) Write the equation which would provide the moment about O produced by the force F (=2 kN). All known values must be included in the equation.
b) Then calculate the value of this moment about O.

3. The frame at right holds a load of sand which can be modeled as a distributed load with a maximum of 800 N/m. The frame is pinned at A, and rests on a frictionless roller at C. Member ABC and ADE are pinned to link BD. Find
a) reaction at C,
b) forces acting on member ABC at B.

4. FBD may be added to the existing picture
The beam is held by rollers at C and pinned at B.
(a) Draw the shear and bending moment diagrams for the beam on the axes provided below ( graded on the magnitude and shape of each segment of the diagrams).
(b) Determine the maximum absolute value of the shear and its location.
(c) Determine the maximum absolute value of the bending moment and its location.
