1 Question 14 of 15 -15 Compute the combined moment of the two 70-lb forces about (a) point O and (b) point A. The moment is positive if counterclockwise, negative if clockwise. Assume a = 8.3 in., b = 3.9 in., F = 70 lb. y I F Answers: 10:5 29°C Mostly cloudy 04/06 Type here to search I O EI 3' U ||| ENG

Determine the magnitude of the moment of the force F={F={50i−24j-80k}N about the base line BC of the tripod. Express your answer to three significant figures and include the appropriate units.

II. Draw the shear and moment diagrams completely for each member of the frame. Indicate the degree of curve and write the equations for moment values. Assume the support A is a pin and D is a roller. Assume that the beam and column connection is fixed.
