To design a cantilevered truss to support the loads shown in the figures, two layouts are proposed as shown in Figs. A and B. All truss members are steel with allowable stress of 20ksi. (a) Determine the minimum cross section area needed for both layouts to prevent buckling (Pcr = p2EI/l2) for the truss with the minimum total weight by using a circular cross section. (b) Which layout has the minimum total weight?
Two bodies of mass 1 kg and 2 kg move towards each other in mutually perpendicular direction with velocities 3m/s and 2 m/s respectively. If the bodies stick together after collisi
Explain the End Cutting Edge Angle It is an angle between the face of the tool and the plane perpendicular to side of shank. It acts as relief angle that is allows only small s
You are required to formulate the loading and boundary conditions using the FE code and evaluate the stress distribution and end deflection of the beam using the ABAQUS code and vi
Assume we want to determine the minimum stopping distance of an automobile traveling at 60 mph. We again assume that the maximum value of µ is unity. Then the maximum deceleration
