Question
In Fig. X3.7.9 the rectangular flashboard MN shown in cross section (a = 5.4 m) is pivoted at B.(a) What must be the maximum height of B above N if the flashboard is on the verge of tipping when the water surface rises to M? (b) If the flashboard is pivoted at the location determined in (a) and the water surface is 1 m below M, what are the reactions at B and N per m length of board perpendicular to the figure?

Question
5–70. The stiff-leg derrick used on ships is supported by a ball-and-socket joint at D and two cables BA and BC. The cables are attached to a smooth collar ring at B, which allows rotation of the derrick about z axis. If the derrick supports a crate having a mass of 200 kg, determine the tension in the cables and the x, y, z components of reaction at D.

Question
Determine the equation for the electric field at the origin caused by a surface distribution with density Ps=cos(theta) located on the surface of a sphere at radius=2m. It would be wise for you to consider the symmetry of the problem, such that only the z-component is non-zero. the x and y components should cancel out (convince yourself of this)
