A death-defying rock climber is scaling a perfectly vertical section of a mountain wall. She used her rivet gun to fix her 6-meter-long rope to the wall so that it is anchored above her. The rope is attached to her waist and the distance between her waist and the bottoms of her feet is I meter. Now she extends her legs perfectly straight and horizontally (with respect to the ground below) so that she is supported by only her rope and the soles of her climbing shoes. The situation is a perfect right triangle, with her rope as the hypotenuse. The climber has a mass of 53 kg. The coefficient of static friction between her feet and the wall is 0.3 g= 9.8 m/s? a. What is the tension in Newtons of her rope at this moment? b. What is the strength in Newtons of the normal force on her feet from the wall?

A cargo ship is loading using a boom crane, which is a 15 m long pole with a cable for lifting cargo which is suspended from the end of the pole. The boom is raised via a cable attached at a point that is 2/3 of the distance to the end of the pole. At one point the crane is lifting an 900 kg crate with the pole making a 30 degree angle with the horizontal, while the cable makes a 40 degree angle with the horizontal. Estimate the tension on the cable.
3m 5m A B 4m Figure 2 4. A thin horizontal beam of negligible mass is hinged at one end A and supported at the other end B by a string, shown in Figure 2. The string can withstand a maximum tension of 30 N. A possum of mass m = 3 kg walks out along the beam. How far along the beam can the possum go before the string breaks?
6m T 10m A 8m Figure 4 A B 6. A horizontal beam AB of mass m = 20kg is supported from end B by a cable and hinged to a A vertical wall at end A. Calculate the magnitude of the tension T in the cable when Batman, who has a mass M = 80 kg, stands midway along the beam. What are the x and y components of the force at the hinge?

A hiker, who weighs 659 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 4280 N, and rests on two concrete supports, one on each end. He stops 1/5 of the way along the bridge. What is the magnitude of the force that a concrete support exerts on the bridge (a) at the near end and (b) at the far end?
The forearm shown below is positioned at an angle with respect to the upper arm, and a 5.6 kg mass is held in the hand. The total mass of the forearm and hand is 2.1 kg, and their center of mass is 16.1 cm from the elbow. (Assume the biceps muscle exerts a force on the forearm that acts vertically.) 5.6 kg B 37.5 cm 4.0 cm (a) What is the magnitude of the force (in N) that the biceps muscle exerts on the forearm for 0-60%7 N (b) What is the magnitude of the force on the elbow joint (in N) for the same angle? N (c) How do these forces depend on the angle 07 The force that the biceps muscle exerts increases and the force on the elbow joint decreases as increases. They both decrease as @ increases. They both increase as increases. They do not depend on 0. The force that the biceps muscle exerts decreases and the force on the elbow joint increases as increases.
In a city park a nonuniform wooden beam 4.00 m long is suspended horizontally by a light steel cable at each end. The cable at the left-hand end makes an angle of 30.0° with the vertical and has tension 620 N. The cable at the right-hand end of the beam makes an angle of 50.0° with the vertical. As an employee of the Parks and Recreation Department, you are asked to find the weight of the beam and the location of its center of gravity.
A fence post of mass m = 8 kg supports a fence with three lengths of barbed wire. The bottom wire is a distance d = 0.35 m from the ground and each wire is a distance 0.35 m above the previous one. Each of these three wires has the tension on it. For this problem, assume that the force exerted by these wires is purely horizontal. An additional guy wire is used to keep the pole upright with a tension of Fa = 490 N. The guy wire attaches to the post at a point h = 0.86 m above the ground and makes an angle of θ = 45 with respect to the horizontal. Write an expression for the tension in any one of the three fence wires. What is the normal force that the ground exerts upward on the post?
