beams Task topic homogeneous subjected to pure bending:

Exercises 4.4 & 4.5

The steel beam shown is made of steel s _And = 250 MPa and s U = 400 MPa . Using a safety factor of 2.50, a) determine the maximum torque that can be applied to the beam when flexed to the axis z .

b) Now suppose that the beam is bent about the center and , determine the maximum torque that can be applied to beam.

Exercise 4.6 & 4.7

A beam that has the section shown is made of an aluminum alloy, s _And = 45 ksi and s U = 70 ksi . Using a safety factor of 3.00, a) find the maximum torque that can be applied to the beam when flexed to the axis z .

Now suppose that the beam is bent with respect to the axis and b) determine the maximum torque that can be applied to the beam.

Exercise 4.8

two vertical forces are applied to the beam cross section shown. Find the maximum forces of tension and compression in the BC portion beam.

Exercise 4.9

two vertical forces are applied to the beam cross section shown. Halle voltage maximum efforts and compression in the BC portion beam.

Exercise 4.10

two vertical forces are applied to the beam cross section shown. Find the maximum forces of tension and compression in the BC portion beam.
