Question 1:
A system of steel pipes is loaded and supported as shown below. If the normal stress in each pipe must not exceed 150 MPa, determine the cross-sectional areas required for each of the sections.
Question 2:
Rigid bar ABC shown below is supported by a pin at bracket A (single shear) and by tie rod (1). Tie rod (1) has a diameter of 5 mm, and it is supported by double-shear pin connections at B and D. The pin at bracket A is a single-shear connection. All pins are 7 mm in diameter. Assume a = 600 mm, b = 300 mm, h = 450 mm, P= 900 N, and ?? = 55°.
Determine the following
a) normal stress in rod (1)
b) the shear stress in pin B
c) the shear stress in pin A
Question 3:
The steel bar shown below will be used to carry an axial tensile load of 400 kN. If the thickness of the bar is 45 mm, determine the normal and shearing stresses on plane AB.
Question 4:
A steel bar with a butt-welded joint, as shown below will be used to carry an axial tensile load of 400 kN. If the normal and shear stresses on the plane of the weld must be limited to 70 MPa and 45 MPa, respectively, determine the minimum thickness t required for the bar.
Question 5:
A 50-mm-wide steel bar has axial loads applied at points B, C, and D. If the normal stress magnitude in the bar must not exceed 60 MPa, determine the minimum thickness that can be used for the bar.
