Q4. The pin jointed truss shown in Figure 24 consists of circular steel members. Each member has a cross sectional area of 750mm and Young's Modulus of 200GPa. The truss is subjected to P KN vertical force at point F acting downwards. The force P is calculated using the formula below using your last digit of your banner ID (in kN): (Last digit of banner ID > 0, P= (Last digit of banner ID = 0, P = 10 x last digit of banner ID P = 100 For example, if your banner ID is 001101115, then P = 10 x 5 = 50kN. (a) Using the principle of virtual work calculate the vertical and horizontal displacement of point F. [20 marks] (b) Sketch the displaced shape of the truss.
