Unformatted text preview: 3. (25 points) The structure shown below is in static equilibrium. It shows a wheel with a diameter of d, and a mass of m. It is held in place by a wire attached to an anchor block at the top of the hill. The wire is parallel to the ground. The contact between the wheel and the wire is smooth. a. Develop and equation for the tension in the wire as a function of the angle of the hill. wheel wire anchor block θ 4. (25 points) The rod (circular cylinders) assembly shown is made of two different diameter bars. It is also subjected to the two loads shown in the Figure. Assume the material follows Hooke’s law. Determine the following. a. The maximum axial and shear stresses in the assembly. b. The overall change in length of the rod due to the applied loads. Young’s modulus is 10x10 6 psi. (Label the various types of equations used in your solution) 100 lb 200 lb 50 in 50 in 0.1 inch dia. 0.2 inch dia. 50 in...
