Alandscaper tries to plumb the tree shown by applying a 54
lbforce. (a) replace the force with an equivalent
force-couplesystem at c. (b) two attempt to plumb the same
tree, with one applying a horizontal force at c and the other
pulling atb. determine these two forces if they are to beequivalent
to the single force in part (a).

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
