Concept explainers
In Figure 11-46 two acrobats perform a balancing maneuver. The arms of the top acrobat (in yellow), together with the weight of his head and shoulders, provide a downward force at a distance of 28 cm from the pivot point to balance the torque produced by his lower body. If the lower body of the top acrobat is modeled as a 54-kg mass at a distance of 39 cm from the pivot point, how much force must the arms and upper body produce?

- A wooden door 2.1 m high and 0.90 m wide is hung by two hinges 1.8 m apart. The lower hinge is 15 cm above the bottom of the door. The center of mass of the door is at its geometric center, and the weight of the door is 260 N, which is supported equally by both hinges. Find the horizontal force exerted by each hinge on the door.arrow_forwardA homeowner is trying to move a stubborn rock from his yard. By using a a metal rod as a lever arm and a fulcrum (or pivot point) the homeowner will have a better chance of moving the rock. The homeowner places the fulcrum a distance ?=0.288 mfrom the rock, which has a mass of 465 kg, and fits one end of the rod under the rock's center of weight. If the homeowner can apply a maximum force of 671 N at the other end of the rod, what is the minimum total length ? of the rod required to move the rock? Assume that the rod is massless and nearly horizontal so that the weight of the rock and homeowner's force are both essentially vertical. The acceleration due to gravity is ?=9.81 m/s2.arrow_forwardA 50 N hand and forearm are held at a 35° angle to the vertically oriented humerus. The CG of the forearm and hand is located at a distance of 12.5 cm from the joint center at the elbow, and the elbow flexor muscles attach at an average distance of 2.5 cm from the joint center. (Assume that the muscles attach at an angle of 35° to the forearm bones.) How much force must the forearm flexors exert if a 50 N weight is held in the hand at a distance along the arm of 25 cm?arrow_forward
- (a) When opening a door, you push on it perpendicularly with a force of 44.0 N at a distance of 0.780 m from the hinges. What torque (in N-m) are you exerting relative to the hinges? (Enter the magnitude.) N-m (b) Does it matter if you push at the same height as the hinges? O Yes O Noarrow_forwardAssuming a single muscle group (biceps) is responsible for carrying a ball with a weight of 5 kg as shown in the image below, what must be the force generated by the biceps so that the elbow is in static equilibrium? The weight of the forearm is 2 kg. The distance between the bicep attachment and elbow is shown as AO = 5 cm, the distance between the center of gravity of the forearm and elbow is BO = 20 cm, and the distance between the ball and elbow is CO = 40 cm.arrow_forwardAn 85-kg basketball player does a series of push-ups to strengthen his arm and chest muscles. If both feet and exert the same force and both palms do, likewise, determine the force that the floor exerts of on each of his feet and on each hand. Assume that his center of mass is 0.920 m from the top of his head.arrow_forward
- A uniform 34.5-kg beam of length e = 4.20 m is supported by a vertical rope located d = 1.20 m from its left end as in the figure below. The right end of the beam is supported by a vertical %3D column. -l- (i (a) Find the tension in the rope. (b) Find the force that the column exerts on the right end of the beam.

Calculate the magnitude of the force in each triceps muscle, and compare it to her weight.arrow_forwardA person bending forward to lift a load "with his back" (Figure a) rather than with his knees" can be injured by large forces exerted on the muscles and vertebrae. The spine pivots mainly at the fifth lumbar vertebra, with the principal supporting force provided by the erector spinalis muscle in the back. To see the magnitude of the forces involved, and to understand why back problems are common among humans, consider the model shown in Figure b, of a person bending forward to lift a W-195-N object. The spine and upper body are represented as a uniform horizontal rod of weight W-295 N pivoted at the base of the spine. The erector spinalls muscle, attached at a point two-thirds of the way up the spine, maintains the position of the back. The angle between the spine and this muscle is 12.0° Back muscle Pivot R₂ T120 T W W₂ 0 (a) Find the tension in the back muscle. KN D (b) Find the compressional force in the spine.

The other end rests against a wall, where it is held by friction (see figure). The coefficient of static friction between the wait and the rod is ,-0.525. Determine the minimum distance from point A at which an additional weight w (the same as the weight of the rod) can be hung without causing the rod to slip at point A 275 x Your response differs from the correct answer by more than 10% Double check your calculations, m Subnd Arowerarrow_forwardThe figure shows an outstretched arm (0.61 m in length) that is parallel to the floor. The arm is pulling downward against the ring attached to the pulley system, in order to hold the 98-N weight stationary. To pull the arm downward, the latissimus dorsi muscle applies the force in the figure, at a point that is 0.069 m from the shoulder joint and oriented at an angle of 29º. The arm has a weight of 43 N and a center of gravity (cg) that is located 0.28 m from the shoulder joint. Find the magnitude of M Axis at houlder joint 29° M 0.28 m 0.069 m 0.61 m 98 Narrow_forward
