A gastrocnemius muscle at optimal length, when maximally stimulated by a single
A gastrocnemius muscle at optimal length, when maximally stimulated by a single electrical stimulus, produces an isometric twitch tension of 80kg, and consumes 5 joules of energy above its basal energy consumption (measured by a calorimeter—includes all the energy used by the muscle as a result of that stimulus).If you then stretch the muscle (hyper-extend it) so that the same maxim

A horizontal beam of negligible weight is simply supported at each end by columns. When a vertical load as placed on a beam 1.00 m from the left end, the vertical upward reaction is the right column is 62.5 N. When the load is increased by 40.0 N, the reaction in the right column increases to 75.0 N. How long is the beam?
