Axial loads are applied to the compound rod that is composeds of an aluminum segment rigidly connected between steel and bronze segments. Find the largest safe value of P if the working stresses are 120MPa for steel, 68MPa for aluminum, and 110MPa for bronze.  Compute “P” due to aluminum capacity. Compute “P” due to bronze capacity. Determine the maximum safest value of “P”

Two rigid materials are bonded together asshown in Figure 1b and beam is subjectedtwo different forces. Determine (a) themaximum tensile and compressive bendingstresses in A-A cross section, (b) radius ofcurvature of the bar.

The 10-mm-diameter steel bolt is surrounded by a bronze sleeve. The outer diameter of this sleeve is 20 mm, and its inner diameter is 10 mm. If the yield stress for the steel is (ay) MPa, and for the bronze (ay)or 520 MPa, determine the magnitude of the largest elastic load P 640 that can be applied to the assembly. E 200 GPa, Ebr= 100 GPa. 10 mm 20 mm Figure 2: Steel Bolt

Puzzler: Most steel reinforcing bars manufactured in the U.S. exhibit a sharp yield plateau. Two exceptions, however, are bars that are quenched and tempered and bars that are coiled immediately after they are hot rolled. The coiled bars are later straightened by a fabricator. Both (1) quenched-and-tempered bars and (2) straightened bars have stress-strain curves that are initially linear, but yielding is gradual, producing what is described as a "round-house" curve. The reason for the round-house behavior is the same for both types of steel. Why do these two types of reinforcing steel exhibit gradual yielding rather than a sharp yield plateau even if the same steel exhibits a sharp yield plateau if it is not quenched and tempered or coiled?

Hand written plzz This is the corresponding tensile stress (MPa) at the minimum strain (as allowed by NSCP2015) of extreme tension steel. Assume f'c-28 MPa and fy-420MPa

1. Three metal strips, each 40 mm height, are bonded together to form the composite beam shown. The modulus of elasticity is 210 GPa for the steel, 105 GPa for the brass, and 70 GPa for the aluminium. If the allowable bending stress for the aluminum (Gallow)al= 100 MPa, for the steel (Gallow)s=150 MPa and (Gallow)b= 200 MPa for brass determine the maximum allowable intensit of w of the uniform distributed load. 2w Aluminum 2w 10 mm Brass 10 mm Steel 20 mm 2m - 40 mm
