Document Summary
Concept: strain: a measure of the ___________________________________________________________ _______________________ of a member that is subjected to a force or set of forces: deflection: when something is caused to _____________________________________________ __________________________________: statically indeterminate: when the _____________________________ in a problem. ______________________________________________________________________________ and therefore other equations must be used. P = force causing deflection/ change in length of member. The rigid bar ad is supported by two steel wires of 1/16-in diameter (e = 29 x 10^6 psi) and a pin and bracket at a. Knowing that the wires were initially taut, determine a) the additional tension in each wire when a 220-lb load. P is applied at d the corresponding deflection of point d b) Link bd is made of brass (e = 105 gpa) and has a cross-sectional area of 240mm^2. Link ce is made of aluminum (e = 72 gpa) and has a cross-sectional area of 300mm^2.
