Chapter 12.3, Problem 76P

Knowing that the allowable normal stress for the steel used is 174 MPa, determine the section modulus and select the most economical S-shaped beam to support the loading shown using the table given.

Knowing that for the beam shown the allowable stress is 12 ksi in ten-sion and 16 ksi in compression, determine the largest couple M that can be applied.

Knowing that for the beam shown the allowable stress is 80 MPa in tension and 100 MPa in compression, determine the largest couple M that can be applied. step by step please!!

A 5-m-long, simply supported steel beam AD is to carry the distributed and concentrated loads shown. Knowing that the allowable normal stress for the grade of steel is 160 MPa, select the wide-flange shape to be used.

Knowing that for the extruded beam shown the allowable stress is 12 ksi in tension and 16 ksi in compression, determine the largest couple M that can be applied.

Determine the maximum load F that can be applied at the free end of a 3 m cantilever beam of universal rolled-steel beam cross-section, 356 mm deep, with a moment of inertia of 142 × 106 mm4, if the allowable stress is 76 MPa.

Using an allowable stress of 155 MPa, determine the largest bend-ing moment Mx that can be applied to the wide-flange beam shown. Neglect the effect of the fillets assuming that the wide-flange beam is bent about the y axis by a couple of moment My

For the wide-flange beam with the loading shown, determine the largest load P that can be applied, knowing that the maximum normal stress is 160 MPa and the largest shearing stress is 100 MPa. W360 x 122 B

For the wide-flange beam with the loading shown, determine thelargest load P that can be applied, knowing that the maximum normal stress is 160 MPa and the largest shearing stress using theapproximation τm = V∕Aweb is 100 MPa.
