1.What is the Distribution reinforcement percentage of area ? Hot to take it for the calculation of distribution reinforcement in dog-legged stair case.
2.the bars of the truss each have a cross0sectional area of 1.25in^2. if the maximum average normal stress in any bar is not toexceed 20ksi. determine the maximum magnitude p of the loads thatcan be applied to the truss
3.The compound shaft consist of Bronze and Steel segments both having120 mm. diameter.If the torque T causes maximum shear stress of 80MPa in the Bronzesegment, determine the angle of rotation of thefree ent. Use G = 83 GPa for Steel and G = 35 GPa for Bronze.
