III. Determine the internal normal force, shear force, and bending moment at point A and point C in the cantilever beam under a linear-distribution force. 200 N/m A B →X 5 m 5 m

The 600-kg uniform I-beam supports the load shown. Determine the reactions at the supports. Answers: Ax Ay = = By = p -7.5 m- +4.5 m 285 kg N N N B

The beam is made of an elastic-plastic material for which σYσYsigma_Y = 70 MPaMPa . The largest moment in the beam occurs within the center section a-a. Determine the magnitude of each force PP that causes this moment to be the largest elastic moment. Determine the magnitude of each force PP that causes this moment to be the largest plastic moment.

Structural member AB is to be supported by a strut CD. Determine the smallest length CD may have, and specify where D must be located for a strut of this length to be used. Take x= 120 mm. 60 mm D. y 20 mm E The smallest length CD may have is mm. The coordinates of point Dare ( and Imm.
