Question 1- In the diagram below, wire segment AB is horizontal. The radius of the loop is 6.00 inches. What is the length of the wire segment AB?
Question 2- Locate the centroid of the figure shown below. (In case you are curious, or have decide to do this by integration, k1 = 0.01458 and k2 = 0.06122).
Question 3- A design studio wishes to have a visually impressive sign which appears to violate physics by having a triangular sign that does not hang along a centroid. (Actually, there is a hallow space covered by a thin film of negligible weight that covers a circular hole of radius R.) If the horizontal axis of the triangle is 2.00 m, if the triangle is 1.50 m wide on the wide end, and if the wire should hang 0.750 m away from the point, and the hole is centered 1.25 m away from the point, what should the radius of the hole be? A possible solution has a hole 0.500 n in radius.
Question 4- If force P = 800 lbs., and distance a = 6.00 ft., determine the force in each member. (Some member will be zero-force members.)
