O Rësources Lx Give Up? Hint The wheels of a wagon can be approximated as the combination of a thin outer hoop, of radius r = 0.262 m and mass 4.32 kg, and two thin crossed rods of mass 8.66 kg each.A farmer would like to replace his wheels with uniform disks ta = 0.0588 m thick, made out of a material with a density of 8290 kg per cubic meter. If the new wheel is to have the same moment of inertia about its center as the old wheel about its center, what should the radius of the disk be? ra = about us privacy policy contact us help careers terms of use

for the below figure, the rod of mass 50kg and length 6m is in the equilibrium. It is hinged to a wall at 0. The rod is at an angle of 40˚ above the horizontal and the rope makes an angle of 70˚ with the rod. (a)find the tension in the rope (b)find the force exerted by the hinge 0 on the rod.

A uniform beam of mass 138 kg and length 7 m is pinned at its left end so that it is free to rotate about that end.  Its right end rests against a vertical, slippery wall such that the beam makes a 57 degree angle with the horizontal.  Calculate the normal force the vertical wall exerts on the beam, in N.  Even though the force points to the left your answer should be a positive number.
