Assume that if the shear stress in steel exceeds about 4.0o x 108 N/m2, the steel ruptures. (a) Determine the shearing force necessary to shear a steel bolt 1.45 cm in diameter. (b) Determine the shearing force necessary to punch a 1.05-cm-diameter hole in a steel plate 0.800 cm thick. Step 1 (a) we know that force F is equal to the surface area A times stress σ so we have 4 108 N/m 2 Your response differs from the...

You are a psychologist who is taking some time away from the city for a while and write a textbook. To do so, you've moved to a very remote, rural area. It is so rural, in fact, that nobody in the entire town has indoor plumbing. As you start to unpack, you are overwhelmed by the stench from your outhouse, and it is such a horrible experience that you begin to rethink every decision you've ever made. Before moving again,...
