Question

Rectangular steel beam, (75) mm wide by (150) mm deep, is loaded as shown in the figure. Determine: a. The maximum fiber stress. b. The stress in a fiber located (25) mm from the top of the beam at midspan. c. For the same beam and loads, if the section of the beam is (80) mm wide by (h) mm deep and the maximum flexural stress is not to exceed (50) MPa, determine the minimum depth (h) of the beam.

Step 1

11 \times 10^6 mm^4\) \(\sigma_{max} = \frac{16 \times 75}{2.11 \times 10^6 \times \frac{150}{2}} = 61.87 MPa\) Show more…
