A 300-lb box is held at rest on a smooth plane by aforce P inclined at an angle =CE=B8 with the plane as shown in the figure. If =CE=B8 45=C2=B0, determine the value of P and the normal pressure N exerted by the plane.NOTE : see fig 7 from the LIST OF FIGURE in Week-1

  • P = 21213 lb , N = 40981 lb
  • P = 21213 lb , N = 40981 lb
  • P = 21213 lb , N = 40981 lb Correct
  • none of the choices
