Answer:
1.933 KN-M
Explanation:
<u>Determine the largest permissible bending moment when the composite bar is bent horizontally </u>
Given data :
modulus of elasticity of steel = 200 GPa
modulus of elasticity of aluminum = 75 GPa
Allowable stress for steel = 220 MPa
Allowable stress for Aluminum = 100 MPa
a = 10 mm
<em>First step </em>
determine moment of resistance when steel reaches its max permissible stress
<em>next </em>: determine moment of resistance when Aluminum reaches its max permissible stress
Finally Largest permissible bending moment of the composite Bar = 1.933 KN-M
<em>attached below is a detailed solution </em>
Answer:
Hook's law holds good up to. A elastic limit. B. plastic limit. C.yield point. D.Breaking point
Answer:
. This is because the injuries can takes place at the time of work.
While lifting heavy objects at the time of work One should divide the loads so that it does not feels burden.
Aids like pulley, handles and wheels can be used to divide the load and weight should be carried in a way that it can be easily carried.
Get manual help with way to heavy loads and the postures should also be maintained at the time of lifting the objects.
