Q.5) A sign is erected on uneven ground supported by cables EF and EG, where point D lies below the x-z plane and G lies above the x-z plane. The tension in cable EG at E is 72 lbs. a) Determine the moment, in vector notation, that the tension force EG creates about the base of the sign AD. b) Compute the same moment vector about AD using a different position vector than part (a) within your cross product.
