Question
Mechanics If the magnitude of the resultant force is to be 9 kN directed along the positive x axis, determine the magnitude of force T acting on the eyebolt and its angle 0. If o = 30°, F, = 5 kN, and the resultant force is to be directed along the positive y axis, determine the magnitude of the resultant force if F, is to be a minimum. Also, what is F2 and the angle 6? 8 kN The beam is to be hoisted using two chains. If the resultant force is to be 600 N directed along the positive y axis, determine the magnitudes of forces F, and F acting on cach chain and the angle e of Fg so that the magnitude of FR is a minimum. F, acts at 30° from the y axis, as shown. The cords BCA and CD can each support a maximum load of 100 Ib. Determine the maximum weight of the crate that can be hoisted at constant velocity and the angle e for equilibrium. Neglect the size of the smooth pulley at C. FA 30° A horizontal force of P = 100 N is just sufficient to hold the crate from sliding down the plane, and a horizontal force of P = 350N is required to just push the crate up the plane. Determine the coefficient of static friction between the plane and the crate, and find the mass of the crate. If the coefficient of static friction at all contacting surfaces is µ, determine the inclination e at which the identical blocks, each of weight W, begin to slide.
