Q: A beam ABCD with a vertical arm CE is supported as a

A beam ABCD with a vertical arm CE is supported as a simple beam at A and D (see figure). A cable passes over a small pulley that is attached to the arm at E. One end of the cable is attac...

Q: Beams ABC and CD are supported at A, C, and

Beams ABC and CD are supported at A, C, and D and are joined by a hinge (or moment release) just to the left of C. The support at A is a sliding support (hence reaction Ay = 0 for the loading shown be...

Q: A beam with simple supports is subjected to a trapezoid ally distributed

A beam with simple supports is subjected to a trapezoid ally distributed load (see figure). The intensity of the load varies from 1.0 kN/m at support A to 2.5 kN/m at support B. (a) Draw t...

Q: A beam of length L is designed to support a uniform load

A beam of length L is designed to support a uniform load of intensity q (see figure). If the supports of the beam are placed at the ends, creating a simple beam, the maximum bending moment in the beam...

Q: The compound beam ABCDE shown in the figure consists of two beams

The compound beam ABCDE shown in the figure consists of two beams (AD and DE) joined by a hinged connection (or moment release) at D. The moment release can transmit a shear force but not a bending mo...

Q: The shear-force diagram for a simple beam is shown in

The shear-force diagram for a simple beam is shown in the figure. Determine the loading on the beam and draw the bending-moment diagram, assuming that no couples act as loads on the beam.
