1. Calculate the magnitude of the moment about the base point O of the 600 N force.

2. The coefficient of static and kinetic friction between the 100kg block and the inclined plane are 0.30 and 0.20. respectively.

Determine a) the frictional force F when P is applied with a magnitude of 200N to the block at rest, b) the force P required to initiate motion up the incline from rest. And c) the friction force F acting on the block if P = 600N.

3. Determine the x and y scalar components of the the forces.

4. Determine the shear force and bending moments.

5. Calculate and draw the Shear force and Bending moment diagrams for the loaded beam and determine the maximum moment M and its location x from left end.

5. Calculate and draw the shear force and bending moment diagram for the cantilever beam shown.

6. The rigid pole and cross-arm assembly is surpoted by the three cables as shown., A turnbuckle at D is tightened until it includes a tension T in CD of 1.2kN. Express T as a vector. Does it make any difference in the result which coordinate system is used?

7. The 70m microwave transmission tower is steadied by three guys cable. Cable AB carries a tension of 12kN. Express the corresponding force on point A as a vector.
