[ANSWERS]-F= 2842.7406 lb-θR= 32.5094° N of E-FV= 2312.7721 lb, 49.4086° wrt y-axis
Determine the value of the force F shown, if the resultant of the five forces acting on particle O has a magnitude of 2.8 kips. What is the direction R of the resultant force? If the resultant force is to be resolved into its components along the positive x-axis and a certain v-axis, the component along the x-axis is 605 lb. What is the magnitude of the other component? Also determine the angle the v-axis makes with the y-axis?
Q2:- During forward stroke of the piston of the double acting steam
engine, the turning moment has the maximum value of 200 N.m
when the crank makes an angle of 80° with the inner dead
center. During the backward stroke, the maximum turning
moment is 150 N.m when the crank makes 80° with the outer
dead center. The turning moment diagram for the engine may be
assumed for simplicity to be represented by two triangles. If the
crank rotates 100 rpm and the radius of gyration of the flywheel
is 1.75 m, find the coefficient of fluctuation of energy and the
weight of the flywheel to keep the speed within + 0.75% of the
mean speed.
