Question 1. Roller at P slides in the slot as a result of the force F = 25 kN. The cross sectional area of both bars is 100 mm2 and E = 200 Gpa. Bar AP has length 0.25 m and bar BP has length 0.2 m. Use the virtual displacement method to determine the axial stress in AP.
Question 2. If the roller and slot in problem 1 is replaced by a pin, use the virtual force method to determine the pin movement in the direction of the force.
Question 3. Use Castigliano's Theorem to determine the reaction force at B and the deflection at A in terms of w, E, I and L.
