Answer #1

2.

considering the moment about foot

w * 0.9 = 1.5 Fh

59* 9.8* 0.9 / 1.5 = Fh

Fh = 346.92 N

equilibrium of forces along vertical

Ff + Fh = mg

Ff + 346.92 = 59* 9.8

Ff = 231.28 N

force on each foot = Ff/2 = 115.64 N

    Constants A 71.0 kg weight lifter is doing arm raises using a 7.50 kg weight in her hand. Her arm pivots around the elbow joint, starting 40.0 below the horizontal. (See the figure(Figure 1).) Biometric measurements have shown that both forearms and the hands together account for 6.40 % of a person's weight. Since the upper arm is held vertically, the biceps muscle always acts vertically and is attached to the bones of the forearm 5.50 cm from the elbow...

    Find the elbow joint reaction force (magnitude and direction) and the elbow flexor muscle force for the instant described below. Assume the forearm, hand, and ball to be a single rigid body. This rigid body has a mass of 3 kg; it has a mass moment of inertia about its center of mass of 0.018 kg*m2 ; its center of mass is 19 cm from the center of the elbow joint. The rigid body has an angular acceleration (α) of...

    How much force (in N) must the biceps muscle exert when a 25.0 kg mass is held in the hand in a stationary position when the arm is 17.4° below the horizontal? Assume the mass of the forearm is 2.46 kg. Distances relative to the elbow joint are reb = 5.12 cm; recg = 16.5 cm; ren = 37.5 cm where the distances are: eb = elbow—biceps; ecg = elbow—forearm center of gravity; eh = elbow-hand. A marble column 0.890...

    In an isometric exercise a person places a hand on a scale and pushes vertically downward, keeping the forearm horizontal. This is possible because the triceps muscle applies an upward force M perpendicular to the arm, as the drawing indicates. The forearm weighs 25.0 N and has a center of gravity as indicated. The scale registers 113 N. Determine the magnitude of M.

    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...
