Unformatted text preview: Using a factor of safety of 3.2, calculate the maximum allowable load P. 43: All members of the truss drawn to the right are 1.00 m long. There are three applied loads, P, Q and R. The magnitude Q is twice P, and the magnitude R is three times P. Each member can support a force of 150 kN in Tension, and the same amount in compression. Using a factor of safety of 1.5, calculate the maximum allowable magnitudes of P, Q and R. A C D B P 4.0ft 3.0ft 3.0ft A B C D E P Q R...
