A tightrope walker is walking between two buildings holding a pole with length L = 14.0 m, and mass m, = 18.5 kg. The daredevil grips the pole with each hand a distance d = 0.575 m from the center of the pole. A bird of mass m, = 545 g lands on the very end of the left-hand side of the pole. Assuming the daredevil applies upward forces with the left and right hands in a direction perpendicular to the pole, what magnitude of force Fieft and Fright must the left and right hand exert to counteract the torque of the bird? Fieft = N Fright N

The wheels,axle, and handles of a wheelbarrow weigh W=56N. The load chamber and it’s contents weigh WL=635N.the drawing shows these two forces in two different wheelbarrow designs. To support the wheelbarrow in equilibrium, the man’s hands apply a force to the handles that is directed vertically upward.consider a rotational axis at the point where the tire contacts the ground, directed perpendicular to the plane of the paper.find the magnitude of the man’s force for both designs.

Consider a teeter-totter that is made out of pine, shown below. A pineapple sits on one side of the teeter-totter, a distance 1.09 m from the pivot point, while an apple (non-pine) sits on the other side, a distance of 2.63 m from the pivot. If the pineapple has a mass 132 g, what must the mass of the apple be in order to balance the teeter-totter (i.e. to maintain rotational equilibrium)? [Answer in units of grams (g) with 3 sig figs but do not enter units with your answer]

The figure below shows a claw hammer being used to pull a nail out of a horizontal board where ? = 27.3°. The mass of the hammer is 1.00 kg. A force of 165 N is exerted horizontally as shown, and the nail does not yet move relative to the board. Assume the force the hammer exerts on the nail is parallel to the nail. A hand uses a hammer to pull a nail out of the ground. The head of the hammer is curved and touches the ground at a single point of contact at the center of the head. The nail in the ground makes an acute angle ? clockwise from the vertical. The nail is hooked in the hammer claw 5.00 cm horizontally to the left of the hammer head's point of contact to the ground. The hand pulls the hammer handle horizontally to the right 30.0 cm above the ground with a force vector F.(a) Find the force exerted by the hammer claws on the nail.magnitude     kNdirection     ° above the horizontal (b) Find the force exerted by the surface on the point of contact with the hammer head.(  î +  ĵ)…
