A mechanic is reinstalling a newly-sharpened blade on a lawn mower. A wedged-in block of wood at C prevents the blade from rotating as the 33-lb force is applied to the wrench handle. The blade is bolted to a bracket attached to the motor shaft O, which protrudes through the bracket and blade. Determine the normal force at C. State any assumptions. Does it matter whether the bolt at Bis installed? 5.1" 33 lb Answer: NC-1 2.02.0 COB

Answer 1
2. To push a 25 kg wooden box up a 30O inclined plane, a man exerts a force of 150 N parallel to the inclined plane. The wooden box slides 5 meters and the coefficient of friction between the wooden box and the inclined plane is 0.25; a. Draw the clear and neat figure of the system. b. Draw the Force diagram. c. Establish the convenient axis and reflect the component of the forces along the axis.

(Newton's laws and their applications) A block with mass m1 slides down an inclined plane whose angle is 22 °, the coefficient of kinetic friction between the block and the plane is 0,250. The block is attached to an ideal rope that passes through two ideal pulleys until it is attached to a fixed support, as shown in figure 3. A rope leaves the axis of the movable pulley up to a block of mass m2 3 m2 m1 Figure 3. Diagram of exercise 3 A. Discuss what difference the exercise will make if one more pulley is placed on the ceiling that makes the rope connect to the rod of the movable pulley.
