A rope is connected to two posts that are separated by a distance d. A person pulls the middle of the rope in a direction that is perpendicular to the line connecting the two posts from an overhead view. A) If the middle of the rope is deflected by a distance of x << d by the person pulling with a magnitude of force F, what is the tension in the rope? B) Find the tension in this rope when...

A person holds a 1.26 N
baseball in his hand, a distance of 34.0 cm from the elbow joint,
as shown in the figure(Figure 1). The biceps, attached at a
distance of 2.75 cm from the elbow, exerts an upward force on the
forearm. Consider the forearm and hand to be a uniform rod with a
mass of 1.40 kg . Suppose the biceps exert just enough upward force
to keep the system in static equilibrium.

2. A person is holding a weight (100 N) in their hand. The weight is a distance of 0.3 meters from the center of rotation of the elbow. If the forearm is parallel to the ground, what is the torque about the elbow due to the weight? If the forearm has an angle of 30° above the horizontal (hand is higher than elbow), what is the torque about the elbow due to the weight? c. If an elbow flexor muscle...

A raft of length Land mass M is a distance d from the dock. At the end closer to the dock stands a person of mass m. For the purpose of getting some numerical values assume that M = 200 kg, m = 50 kg, L = 10 m, d = 4 m. a) As the person walks the center of mass of the system doesn't change. Explain why. b) The person walks to the other end of the raft....
