Statics Problems

Problem 1: The window is held open by chain AB. Determine the length of the chain, and express the 50-lb force acting at A along the chain as a Cartesian vector. Determine its coordinate direction angles.



Problem 2: The cords BCA and CD can each support a maximum load of 100-lb. Determine the maximum weight of the crate that can be hoisted at constant velocity, and the angle q for equilibrium.



Problem 3: The 2500-N crate is to be hoisted with constant velocity from the hold of a ship using the cable arrangement shown. Determine the tension in each of the three cables for equilibrium.




Problem 4: Determine the force in members BC, FC, and FE and state if these members are in tension or compression.




Problem 5: Determine the normal force, shear force, and moment at a section passing through point D of the two-member frame.
