2. A rectangular beam, 400 x 600 mm gross dimension, is cast using a concrete strength of fc 30 MPa, reinforced with 5-25 mm diameter steel bar at the effective depth of 500 mm. If is subjected to a moment, M 130 kN-m. Determine the following: Magnitude of the bending moment that cracks the singly-reinforced beam section. (10 pts) b. For the computed cracking moment, determine the maximum compressive stress in the concrete and the stress in the tension steel....
draw the section views (A-A) and (B-B) and dimension both views properly. (all dimensions are im (mm) ) . Draw the section views (A-A) and (B-B) and dimension both views properly. Use the proper hatching rules for the hatched portions. All dimensions are in (mm)
A space frame strut has a rectangular cross section of 10.0 mm by 30.0 mm that is made from 1040 cold drawn steel. It sees a load that varies from a tensile force of 20.0 kN to a compressive force of 8.0 kN. If the part needs to have a reliability factor of 99%, what is the design factor using the Goodman Method? Use the larger dimension (30.0 mm) for the size factor in this problem.
