Question

Determine the load P if the end C is displaced 0.075 in. downward.

Expert Solution

Step 1: Dtaw the triangle diagram.

The triangle ABD is

the deflection at point d is -

$fraction numerator 0.075 over denominator 6 end fraction equals delta over 3 delta equals 0.0375 space in$

Using the cosine rule, find the value of new length.

$table row cell B D to the power of apostrophe end cell equals cell open parentheses 5 cross times 12 close parentheses squared plus open parentheses 0.0375 close parentheses squared minus 2 open parentheses 12 cross times 5 close parentheses open parentheses 0.0375 close parentheses cos 143.13 end cell row blank equals cell 60.03 space in end cell end table$
