Problem Statement Based on Problem 4-61 from the textbook. Determine the magnitude of the moment of the force F about the base line AB of the tripod. a=3.6m b=0.6m F= 40i -25j -80k 2.5 m

Only handwritten answer is needed please

Also, determine angle that T makes with the positive y-axis. Your answer should be in the range 180 ≤ ang > -180. Also, determine angle that T makes with the positive z-axis. Your answer should be in the range 180 ≤ ang > -180.
