1.Determine the moment of the force F about an axis extending between A and C as shown in Fig.1.Express the result as a Cartesian vector.

2.If the couple moment acting on the pipe has a magnitude of 400N-m(Fig.2),determine the magnitude of F of the vertical force applied to each wrench.

3.Determine the tension in each segment of the cable and the cable's total length(Fig.3).

4.Locate the centroid X and Y of the shaded area shown in Fig.4.

5.A circular steel bar subjected to a torques T at the ends has diameter d=1.5in,length L=54in,and shear modulus of elasticity G=11.5*10(6)psi.

6.If the torque T=250lb-ft,calculate the maximum shear stress in the bar and the angle of twist between the ends.

7.If the allowable shear stress is 12000 psi and the allowable angle of twist is 2.5度,what is the maximum permissible torque?

8.Determine the maximum tensile stress and maximum compressive stress due to the losd P action on the simple beam AB(see figure).
