For the following beam rebar is grade 60 and compressive strength of concrete is 3 ksi. if the beam is to be exposed to moist air is the crack width satisfactory as compared to the values permitted by the aci code. calculate the crack width from two different methods precisely. revise the design of reinforcing and recompute the crack width.

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

uranium fissions/breaks up giving out energy and neutrons

this would be about 43%
