Chapter 5, Problem 15E
Studies of gymnasts show that their high rate of injuries to the Achilles tendon is due to tensions in the tendon that typically reach 10 times body weight. That force is provided by a pair of muscles, each exerting a force at 25° to the vertical, with their horizontal components opposite. For a 55-kg gymnast, find the force in each of these muscles.

Hi I needed help with this.
An athlete with a mass of 53.5 kg is doing pushups as shown in the figure below. The value for rW⊥ is 1.00 m and the value for rR⊥ is 1.60 m.
(a) Assuming she moves upward at a constant speed, determine the force she must exert on the floor with each hand to do a push-up.(b) The triceps muscle in the back of her upper arm with an effective lever arm of rT⊥ = 1.70 cm, as shown in the figure below, and she exerts force on the floor a horizontal distance of r 'R⊥ = 2.05 cm from the elbow joint.
Determine the force in the triceps muscle.In order to appreciate the strength of the triceps, determine the ratio of the force in the tricep muscle to her weight (in decimal form).
FT/W = ?
When landing from a jump, Andy applied an average vertical force of -2500 N to the ground in order to slow down the vertical velocity of his center of gravity. What was the average acceleration of his center of gravity in the vertical direction once ground contact was made? (weight = -760 N; mass = 77.5 kg)
(a) A 5.5 kg salami is supported by a cord that runs to a spring scale, which is supported by another cord from the ceiling . What is the reading on the scale, which is marked in SI weight units? (This is a way to measure weight by a deli owner.) N(b) the salami is supported by a cord that runs around a pulley and to a scale. The opposite end of the scale is attached by a cord to a wall. What is the reading on the scale? (This is the way by a physics major.) N(c) the wall has been replaced with a second 5.5 kg salami on the left, and the assembly is stationary.

- On her way to visit Grandmother, Red Riding Hood sat down to rest and placed her 1.20 kg basket of goodies beside her. A wolf came along, spotted the basket, and began to pull on the handle with a force of 6.40 N at an angle of 25 degree with respect to vertical. Red was not going to let go easily, so she pulled on the handle with a force of 12.2 N. If the net force on the basket is straight up, at what angle was Red Riding Hood pulling from the vertical?arrow_forwardQuestion 19 In order to prevent muscle contraction from misaligning bones during healing (which can cause a permanent limp), injured or broken legs must be supported horizontally and at the same time kept under tension (traction) directed along the leg. One version of a device to accomplish this aim, the Russell traction apparatus, is shown in the figure below. This system allows the apparatus to support the full weight of the injured leg and at the same time provide the traction along the leg. If the leg to be supported weighs 47.0 N, what must be the weight of W? 25° 25° W Question 20 In order to prevent muscle contraction from misaligning bones during healing (which can cause a permanent limp), injured or broken legs must be supported horizontally and at the same time kept under tension (traction) directed along the leg.

In the design of a supermarket, there are to be several ramps connecting different parts of the store. Customers will have to push grocery carts up the ramps and it is obviously desirable that this not be too difficult. The engineer has done a survey and found that almost no one complains if the force directed up the ramp is no more than 20 N. Ignoring friction, at what maximum angle should the ramps be built, assuming a full 30-kg grocery cart?arrow_forward

She uses a scale to measure the tension in the rope as she changes the angle at which she pulls, while always keeping the 15 kg mass at exactly the same spot Compare the tension in the rope when it makes an angle of 30° with respect to the vertical with the tension in the rope when it makes an angle of 60° with respect to the vertical. Her friend, Zora, now takes an identical mass and attaches hers directly to the ceiling with just a rope.
