Four coplanar vectors act at a point. A 20.0N vector is directed 20° to the positive x-axis, a 50.0N vector acts at -30°, a 40.0N vector acts at 150° and the fourth vector is directed at 250°. Obtain the value of the equilibrrant vector( a single vector that cancels the combine effect of the above vectors).​

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
