425 lb A steel tank is to be positioned in an excavation. Knowing that a 20°, determine by trigonometry (a) the required magnitude of the force P if the resultant force is vertical, (b) the corresponding magnitude of 30°
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.
P.2 Two forces are applied as shown to a hook support. Knowing that the magnitude of P is 35 N, determine by trigonometry (a) the required angle a if the resultant R of the two forces applied to the support is to be horizontal, (b) the corresponding magnitude of R. Cs 25°

Two forces P and Q are applied to the lid of a storage bin as shown. Knowing that P = 48 N and Q = 60 N, determine by trigonometry the magnitude and direction of the resultant of the two forces.
A trolley that moves along a horizontal beam is acted upon by two forces as shown. Determine by trigonometry the magnitude and direction of the force P so that the resultant is a vertical force of 2.5 kN.
The tank contains a fluid with a specific weight of 80.7 lb/ft3 . Determine (a) magnitude of the resultant force exerted by the fluid on the bottom of the tank; (b) magnitude of the resultant force exerted by the fluid on side ABCD; (c) location of the center of pressure on side ABCD (vertical distance below liquid surface); (d) magnitude of the resultant force exerted by the fluid on side AEFD; (e) location of the center of pressure on side...
Your tree is at risk of falling over. You decide to tether two ropes to stabilize it. One rope has a tension of T1= 250 lb and is positioned at alpha=75° from horizontal, as shown in the figure below. The other rope must be tethered at beta=55° from horizontal, as shown. Determine how much tension, T2, must be applied to the second rope to ensure that the resultant of the two forces is vertical. What is the magnitude of the...
