You cannot walk over deep snow in regular shoes without sinking deeply into the snow. Instead, you walk with snowshoes (Fig. 12.71). For a person with the body weight of 170 lb on a single foot (while walking), what is the stress under a shoe in psi (pounds per square inch) for (a) a standard shoe measuring 11 in. by 4.0 in. and (b) a snowshoe measuring 26 in. by 9.5 in.? Assume a rectangular area for each shoe. (c) By what percentage does the snowshoe reduce the stress?
π Solution Approach
Given: 170 lb, 11 in, 4.0 in, 26 in, 9.5 in
Find: (a) a standard shoe measuring 11 in; (b) a snowshoe measuring 26 in; (c) By what percentage does the snowshoe reduce the stress?
This problem covers key concepts in Equilibrium and Elasticity from Fundamentals of Physics Extended 12th Edition by Halliday, Resnick & Walker. The step-by-step solution involves applying fundamental principles and systematic analysis to arrive at the correct answer. Full solution available with a Solution Pass.
