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 are applied as shown to a hook support. Knowing that the magnitude of P is 35 N, determine by trigonometry (a) the required angle α if the resultant R of the two forces applied to the support is to be horizontal, (b) the corresponding magnitude of R.
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...
Two forces are applied as shown to a hook support. Knowing that the magnitude of P is 40 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.
