A 4.0- m-long iron bar of uniform cross section is held
perpendicular to the wall by a wire from the end of the bar to the
wall (see the figure). The bar is fastened to the wall with a
hinge. What is the tension in the wire if the iron bar weighs 700 N
and the wire is 5.0 m long?

A bar ABCD with varying cross section and subjected to axial loads is shown schematically in Figure Q3. Take modulus of elasticity of bar as 202 GPa. The length of each section L1 = 111 mm; L2 = 205 mm; and L3 = 451 mm. The cross sectional dimensions are as follows: Section 1 is square with side 49 mm, Section 2 is circular with diameter 79 mm and Section 3 is circular with diameter 32 mm. The forces are...
The bar has a 40 mm by 20 mm rectangular cross section. The allowable normal and shear stresses on inclined surface a-a must be limited to 55 MPa and 30 MPa respectively. Determine the magnitude of the maximum axial force P that can be applied to the bar, and determine the actual normal and shear stresses acting on inclined plane a-a (MPa)
