STATICS PROBLEMS


Hwk Set #1. (Due January)
3 Problems from Chapter 5
Text: 5.76,5.89,5.103


Hwk Set #2. (Due February 1)
2 Problems from Chapter 6
Text: 6.3 (Set up and solve by hand) , 6.36 ( Just set up equations for reactions and joint equilibrium, do not solve).

Computer: Solve Problems 6.3 and 6.35/6.36 using Matlab and Method of Joints.
For 6.3, consider at least two other positions of point C to determine which maximizes the force in member BC.
For 6.35/6.36, solve using combined loadings and show that superposition of loads in 6.35/6.36 gives same result as combined loading case.
