425 30 Fig. P2.11, P2.12 and P2.13 2.13 A steel tank is to be positioned in an excavation Determine by trigo nometry (a) the magnitude and direction of the smallest force P for which the resultant R of the two forces applied at A is vertical, (b) the comesponding magnitude of R
Vector mathematics Do not round intermediate calculations, however for display purposes report intermediate steps rounded to four significant figures. Give your final answer(s) to three significant figures. A steel tank is to be positioned in an excavation. Determine by trigonometry (a) the magnitude and direction of the smallest force P for which the resultant R of the two forces applied at A is vertical, (b) the corresponding magnitude of R. Round your answer to the nearest whole number.
