A rigid bar AB is pinned at end A (double shear) and is supported by a rod CD and loaded by a force P-30KN at end B. a) Determine the required diameter of the pins at A if D. the allowable stress in shear is 120MPA. b) Find the required cross-sectional area of rod DC if the allowable normal -2b stress is 230MP.. Consider load P only; ignore the weight of bar ADB and the cables. c) If the tube modulus of elasticity is 200Gpa what is the vertical displacement of point D. (Consider the area of the rod calculated in par (b)) CD section Activate Windows Go to PC settings to activate Windows b=3m and L=4m.
