The moment of a certain force F is 240N-m counter-clockwise about O and 160N-m clockwise about B. If its moment about A is zero, determine the force.

Part I. Principle of Superposition. For the beam loaded as shown, it is required to determine the distribution of internal forces and moments on the beam. El is constant. The supports at B and C are rollers and D is pinned. 10 kN 3 kN/m 3 kN/m В A 3m 3m D 3m 4 kN 1. Determine the degree of indeterminacy of this beam. 2. Solve for all the support reactions. 3. Draw the shear and bending moment diagram for the beam.

Please do this carefully.

A clockwise couple M = 5 N ⋅ m is resisted by theshaft of the electric motor. Determine the magnitude of thereactive forces -R and R which act at supports A and B sothat the resultant of the two couples is zero.
