Flexural stress (Shishir Sir's Lecture)

00:00 - 1. A beam 150 mm wide by 250 mm deep supports the load shown in figure. Determine the maximum flexural stress.
09:10 - 2. A timber beam 4 in wide by 12in high and 20ft long carrying the load shown in figure. if the maximum flexure stress is 1007 psi, for what maximum value of w will the shear be zero under P, and what is the value of P?​
17:18 - 3. Determine the minimum height h of the beam shown in figure if the flexural stress is not to exceed 20MPa.
23:59 - 4. A 50-mm diameter bar is used as a simply supported beam 3 m long. Determine the largest uniformly distributed load that can be applied over the right two-thirds of the beam if the flexural stress is limited to 50 MPa.
