PROBLEM 3. (20 points) GIVEN: Angled bar OABC is loaded with a point couple at A, a distributed load from B to C and a point load at C as shown. The bar is held in static equilibrium by a fixed support at O. FIND: a) For the distributed load, determine the magnitude of the equivalent force and the location of the force above the x-axis.
