- Solve the preceding problem if F =90 mm, F = 42 kN, and t = 40°MPaarrow_forwardThe stresses on an element are sx= 1000 Psi. sy= 500 psi, and txy= 350 psi. Find the stresses acting on an element oriented at an angle 0 = 250. Show these stresses on the rotated element.arrow_forward3. A mild steel rod supports a tensile load of 50 kN. If the stress in the rod is limited to 100 MPa, find the size of the rod when the cross-section is 1. circular, 2. square, and 3. rectangular with width = 3 × thickness.arrow_forward

Calculate the normal stress in the rod. Provide your answer to 2 decimal places in MPа. Rod diameter = 25mm В y F kNarrow_forwardTwo solid cylindrical rods support a load of P = 39 kN, as shown. Rod (1) has a diameter of 16 mm and the diameter of rod (2) is 11 mm. Determine the axial stress in rod 2. Assume a = 2.2 m, b = 4.6 m, c = 2.7 m, and d = 2.4 m. Use positive for tensile stress and negative for compressive stress. Express your answer in MPa rounded to the nearest whole number.arrow_forwardA tie rod of ¼ inch diameter is used to hold a plaster wall in place. The tensile stress in the rod caused by load P is 20 ksi. Find the diameter “d” (to the nearest 1/6 inch) of the washer that keeps the bearing stress between the plaster and the washer from exceeding 300 psi.arrow_forward

The modulus of elasticity of steel is 200 GPa. Calculate the stress in the wall of the container.arrow_forwardTwo vertical rods one of steel and the other of copper are each rigidly fixed at the top and 50cm apart. Diameters and lengths of each rod are 2cm and 4m respectively. A cross bar fixed to the rods at the lower ends carries a load of 5000 N such that the cross bar remains horizontal even after loading.

Spring specifications are as follows: wire diameter=25 mm, outside coil diameter= 230mm, no. of active coils=8; and wire diameter=20 mm, outside coil diameter= 170mm, no. of active coils=20. Take G= 79 GPa. Determine the force exerted by each spring and the stress induced in each.arrow_forwardA circular tube AB is fixed at one end and free at the other end. The tube is subjected to axial force at joint B. If the outer diameter of the tube is 5 in. and the thickness is 3 - in., calculate the maximum normal stress in the tube (in ksi).
