You are designing a method to help lift a 1,956 lbf rocket (1 ton) for transportation. You are trying to decide on the best way to use "-20 steel bolts with a yield strength of 50 ksi to hold the rocket. In each case you are designing to have a factor of safety of 2. How many bolts are needed if the bolts are put in single shear directly on the shank of the bolt? Use the shank diameter (1/4 inch) for calculating the area. Provide your answer with partial bolts. For example if you need 2.5 bolts to get exactly a factor of safety of 2, give 2.5 even though in practice you would need to use 3 bolts in your design. Do this for all problems.
