    Machine part ABC is supported by a frictionless hinge

    So would the Moment about B or Mb = (-120x8) + (Nx10) work to find the normal force?

    Machine part ABC is supported by a frictionless hinge

    thats where I got stuck actually : / I know that to find the friction you would have to have a normal force to multiply M=0.2 by, I'm just not sure how to find the normal force : /

    Machine part ABC is supported by a frictionless hinge

    The machine part ABC is supported by a frictionless hinge at B and a 10degree wedge at C. There is also a 120 lb force pushing to the right of point A. Knowing that the coefficient of static friction is 0.20 at both surfaces of the wedge, determine (a) the force P required to move the wedge to...
