The part shown is loaded at point B with 300 lbf in the negative y direction, at point C with 200 lbf in thenegative z direction, and at point D with a force with components of 60 lbf in the positive x direction and 75 lbfin the positive y direction. The diameter of the bar AB is 0.75 in. Evaluate the likelihood of failure in bar AB byproviding the following information:(a) Determine the precise location of the critical stress element at the cross section at A (i.e., specify the radialdistance and the angle from the vertical y axis.)(b) Sketch the critical stress element and determine magnitudes and directions for all stresses acting on it.(c) For the critical stress element, determine the three principal stresses and the maximum shear stress.200 lbf0.75-in dia300 lbf6 in75 lbf5.5 in5 in60 lbf

A 330 gram ball is attached to one end of a rubber (Young's Modulus= 0.120 GN/m2) wire of diameter 1.32 mm and an unstretched length of 83.0 cm. The other end of the wire is attached to the top of a post. The ball rotates around the post in a horizontal plane such that the angle between the wire and the horizontal is 10.5 degrees. Find the tension in the wire and the increase in the wire's length due to the tension in the wire. Tension 17.75 Vo N %3D ALength = cm
Between each pair of vertebrae in the spinal column is a cylindrical disc of cartilage. Suppose that such a particular disc of cartilage has a a radius of 3.118 cm (100cm = 1 meter) and a thickness of 6.877 mm (1000mm= 1meter). The shear modulus of cartilage is 1.2 × 107 N/m2. Suppose that a shearing force of magnitude 9 N is applied parallel to the top surface of the disc while the bottom surface remains fixed in place. How far does the top surface move relative to the bottom surface in microns (1 meter = 106 microns)?

The illustrated belt is made of rubber (E= = 4 MPa) and has a thickness of 4 mm. It passes through a pulley whose diameter is 20 cm. The belt is subjected to a tension of 50 N. What must be the minimum width, L, so that the stress does not exceed 200 kPa? Answer: 10.3 cm
A 1.25 m long cable has a diameter 3.50 mm with a Young’s Modulus, E, of 9.75 x 109 N/m2 . When the wire is placed under tension, it experiences a stress of 202.52 x 106 N/m2 , the length of the cable extends by 36.35 mm. Calculate the force that the cable experiences under tension and the strain energy density (U/V) due to deformation. Give your answers in newtons (N) to 2 decimal places for the force; and in joules per cubic metre (J/m3 ) for the strain energy density to 2 decimal places. Assume the cable is solid and the material is homogeneous.
