a) Two bars of different size form a pin-connected frame that supports a Load 'P' at point A as shown in the Fig. 3. What safe load P (kN) can be applied if the allowable stress of 120 MPa is not to be exceeded? Assume buckling has been prevented. Allowable stress is based on a factor of safety of 2.0.
