2.11 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 R of the two forces applied at A is to be vertical, (b) the corresponding magnitude of R. Answer 425 lb 30° A

2.10 Two forces are applied as shown to a hook support. Knowing that. 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. Answer 50 N P 25° a G
