A crane is used to lift a crate weighing 1,000 N. The cable that lifts the crate has a radius of 5.64 mm. The initial length of the cable is 30 m when it is subject to the full weight of the crate.
a. When the cable is lifting the full weight, what is the stress in the cable?
b. How much will the cable stretch if it is made from titanium (E = 114 GPa, Yield Stress = 140MPa)?
c. How much will the cable stretch if it is made from nylon (E = 3.75 GPa, Yield Stress = 63.6 MPa)?
d. For each material, what is the minimum cable diameter that can be used to lift the weight before it yields?
