You are playing basketball with some friends at the park when Nate Robinson, the 180 lb(f) former New York Knicks point guard and only three-time winner of the NBA Slam Dunk Contest, stops by. You are curious about the forces the members of the hoop apparatus experience during a dunk. If Nate dunks and hangs on the rim of the hoop, find the forces supported by each member of the apparatus and the support reactions at D. Member IJ is a hand crank which can be used to adjust the height of the rim, and it acts as a two-force member. Post ABCD weighs 400 N and has a center of mass at point C. The assembly EFGH weighs 220 N and has a center of mass at point G

Direction: Circle T to indicate true statements or F to indicate false statements. Copper is not a conductor of electricity because only materials that are magnetic can conduct electricity.

A beam is part of the framing system for the floor of an office building. The floor is subjected to both dead loads and live loads. The maximum moment caused by the service dead load is 45 ft-kips, and the maximum moment for the service live load is 63 ft-kips (these moments occur at the same location on the beam and can therefore be combined). a. If load and resistance factor design is used, determine the maximum factored bending moment (required moment strength). What is the controlling AISC load combination? b. What is the required nominal moment strength for a resistance factor of 0.90? c. If allowable strength design is used, determine the required moment strength. What is the controlling AISC lead combination? d. What is the required nominal moment strength for a safety factor of 1.67?

using Figure 5-27, what is the advantage of the suspended type magnet over the other two types of magnets?
