SEMESTER II SESSION 2014/2015EXERCISE 3 (SUPPORTS)1) Determine
the reactions on the beam with pin support at A and roller support
at B.
2) Determine the reactions on the cantilevered beam.
3) Determine the reactions at A, B, and C. Assume that the
connection at B is a pin and C is a roller
4) Determine the horizontal and vertical components of reaction
at the pins A, B, and C of the two-member frame.
