When P1 = 6.8 kips and P2 = 10.8 kips. [A kip is a US customary unit of force. It equals 1000 pounds-force] Calculate the forces in members AD, CD and CE of this truss system A roller support is at B and a simple pin support is at K (Round the final answers to three decimal places.) P B 15 ft 15 ft 15 ft P P The force in AD is The force in CD is The force in CE is C D kips. (Compression) kips. (Tension) G H K 8 ft A cantilever beam is supported by a fixed end at A and is exposed to a load at the free end. The beam is loaded by distributed loads as shown and by point load B. Determine the reactions at the beam supports when the point load B is 480 lb. (Round the final answers to the nearest whole number.) 20 inches 12 inches 50 lb/ft pertin beam A The reaction at the beam support A is The moment MA at the beam support A is 6 inches lb. lb.in. B
