1.Two bolts are used to form a joint connecting rectangular bars in tension. The top and bottom pull to the left with 10 kips each, the middle part 20 kips to the right. The bolts have a diameter 3/8 inch, determine the average shear stress on the bolt surfaces that are subjected to direct shear.
2.A Ferris wheel with a radius of 35 feet starts from rest and undergoes an angular acceleration of 0.05 rad/s^2. Compute the magnitude of the velocity and acceleration vectors at 5 seconds for a point on the rim of the Ferris wheel. Also make a sketch of the velocity and acceleration vectors.
