Rigid beam ABC supports two rods that initially have no strain. If a temperature increase in rod (1) creates a normal strain of 2,337 μin./in. in it, determine the normal strain in rod (2). The initial lengths are a = 11 in., b = 12 in., c = 38 in., and d = 11 in. Assume there is no slack in the connections.

Which branch of the military recognized the need to retain PTs in an organized unit to provide service to military personnel?

All of the following had a direct impact on the delivery of physical therapy, except:

A Bush’s Best can weighs 1.06 lb and is 2.94 in. in diameter. A Ro-Tel can weighs 0.75 lb and is 2.52 in. in diameter. What is the largest bearing stress that occurs between the cans and the table? Assume each can has a smooth base and sits flat on the table.

A Ro-Tel can weighs 0.79 lb and is 2.50 in. in diameter. A Libby’s can weighs 1.05 lb and is 2.94 in. in diameter. What is the largest bearing stress that occurs between the cans and the table? Assume each can has a smooth base and sits flat on the table.

Rigid beam ABC supports two rods that initially have no strain. If a temperature increase in rod (1) creates a normal strain of 2,349 μin./in. in it, determine the normal strain in rod (2). The initial lengths are a = 9 in., b = 16 in., c = 31 in., and d = 8 in. Assume there is no slack in the connections.
