A solid steel bar of circular cross section has diameter d = 40 mm, length L = 1.3 m and shear modulus of elasticity G = 80 GPa. The bar is subjected to torques T acting at the ends. If the torques have magnitude T = 340 Nm, what is the maximum shear stress in the bar? What is the angle of twist between the ends? If the allowable shear stress is 42 MPa and the allowable angle of twist...
60 min 30 mm 2. Problem #2: (30 points) A torque T = 3kN-m is applied to the solid bronze (G=3000ksi) cylinder shown. Determine: (a) (10 points) The maximum shear stress. Polar moment of inertia is given by formula: J = #D/32, where Dis the diameter of the cylinder. (b) (10 points) The shear stress at point D, which lies on a 15-mm radius circle drawn on the end of the cylinder. (c) (5 points) Sketch the shear stress distribution...
PROBLEM 2: 40% A 6 kN force is exerted on the frame which has the T cross sectio analyze the states of stress at a section taken at 800 mm from the point of n shown below. It is required to 1. For the given T cross section, find the centroid and the area moment of inertia I,. 2. Draw the free body diagram of the free end of the frame and determine the interna loadings at the centroid of...
1) Use equilibrium to solve for the unknown torque at Point C of the problem in the Appendix. Sum moments about the X-axis and given that the shaft is in equilibrium, determine the torque that must be applied at Point C. You can assume that the shaft is not connected to any other features although in a real-world application there would need to be bearing that keep the shaft from ‘wandering off.’ But note that there are no ‘forces’ applied...
