The rigid bar ABCD is suspended from three identical wires as shown. The cross-sectional are of each wire is A, the unloaded length of each wire is L, and the elastic modulus is E. Knowing that a = b, determine the deflection in wire A, B and D caused by the load P applied at C.© BrainMass Inc. brainmass.com October 24, 2018, 9:02 pm ad1c9bdddf
The deflection of a wire in a rigid bar is determined.
Determine the stress in a stay at a given temperature
A steel 'stay' of effective length 5m is fitted in between the walls of a ships refrigerated compartment when the temperature is 18 degrees centigrade.
Assume zero stress in the stay on completion of fitting. when the temperature falls to -10 degrees centigrade, the gap between the walls is reduced by 0.5mm.
Determine the stress in the 'stay' at this temperature.
Coefficient of linear expansion = 11 x 10^-6 per degrees centigrade.
Modulus of Elasticity = 210 GN m^-2View Full Posting Details
