35° 35° 1) The diagram above shows a variation of the Russel Traction Apparatus, which is used to apply traction to a broken femur. If a physical therapist specifies that the traction force along the leg is to be 35 N, then what weight w would need to be hung from the apparatus?

Select all that are True. Pulleys cannot be used to redirect tension forces. Pulleys can be arranged to amplify a tension force, to make lifting objects easier. Pulleys can be used to redirect tension forces. Pulleys cannot "give you something for nothing", so they cannot be used to amplify forces to make lifing objects easier. The tension on either side of a massless pulley must be the same. The tension on either side of a massless pulley must be different.

A system of two cables supports a 1$0-N ball as shown. 30° 150 N What is the tension in the right-hand cable? A) 260 N B. 300 N C) 170 N 87 N

Describe the factors that cause static friction between two surfaces to increase.

A person exerts a horizontal force of 190 N in the test apparatus shown in the figure. Find the horizontal force that his flexor muscle exerts on his forearm. Number i Units 0.34 m Flexor muscle M 190 N 0.054 m Elbow joint
