There’s always a but. We decided yesterday in class that we would have no more collected homework this semester, and we would instead use the time for the project. But you did ask for some suggested problems out of Ch. 8 and 9, so here they are:
Ch. 8: 8-26/27, 8-34, 8-37 (looks […]

Problem 7-26, 7-54
Note that 7-26 really is a shear STRESS problem, even though the problem […]

Introduction to bending. This is a good one! The discussion about the radius of curvature, the nature of the deformation, the neutral axis, and all the rest…there’s alot of good mechanics here. There is an important but slightly less energetic discussion of sign conventions. In any case, the mechanics here are […]

This is a mashup of strength of materials content and statics content. It’s really a bridge lecture from Chapter 5 to Chapter 6, and as such it contains some of each. Have a look at the stress concentration stuff (just like in Ch. 4), and then spend some time reflecting on the shear […]
