Rebar is often made of steel and is commonly used to reinforce concrete.
One of the rebar pieces has a circular cross-sectional area, a Young's Modulus of 198 gigapascals [GPa),
and yields at a force of 27 kilopounds-force [kip].
At this force, the rebar has a strain of 0.00367 inches per inch [i].
Determine the radius of the rebar in units of inches [in].

- You have 4 springs, one each 3.5, 6, 8.5, 11 newtons per meter. How close an equivalent stiffness to the average of the four springs (7.25 newtons per meter [N/m]) can you make using only these springs? You may use all four springs to do this, but you may use less if that will yield an equivalent stiffness closer to the average.arrow_forwardA crane is pulling a car, exerting a force F = 6072 [N] with the chain at an angle θ = 31 ° with the ground.
