A man is holding a 19-kg child using both hands with his elbows bent in a 90∘ angle. The biceps muscle provides the positive torque he needs to support the child. Determine the force that each of his biceps muscles must exert on the forearm in order to hold the child safely in this position. Ignore the triceps muscle and the mass of the arm. Let the child be l = 0.35 m from the elbow joint, and the biceps...
A3.1 RB Kinematics -Rotating reference fromes (Advanced) An athlete exercises his arm by raising the 8-kg mass m. The shoulder joint A is stationary. The distance AB is 300 mm, the distance BC is 400 mm, and the distance from C to the pulley is 340 mm. The angular velocities w 1.5 rad/s and 2 rad/s are constant. What are the velocity and acceleration of the weights?

wall length of Ladder=7.om man on middle of ladder mass of man man Ladder's center of ma 2.5mm floor 3. 2 m Static Equilibrium - Ladder Comprehensive As shown in the figure, the top of a 7.0-m long ladder (mass 2 = 20 kg) leans against a frictionless wall. The bottom of the ladder rests on a rough floor, with 3.2 m from the wall. The distance from the ladder's center of mass to its bottom end is 2.5 m...
A right triangle has hypotenuse 13 cm and one side 7 cm. Find the length of the other side, and the sine, cosine and tangent of each of the other two angles. A man running 4 m/s is passed by a car at 20 m/s, both heading East. What is the velocity of the man relative to the car? How far apart are the 20 seconds after the car passes the man? A ball is thrown vertically upwards from the...
Question 25 of 30 > A tightrope walker is walking between two buildings holding a pole with length L = 16.0 m, and mass mp-20.0 kg. The daredevil grips the pole with each hand a distance d = 0.500 m from the center of the pole. A bird of mass m 575 g lands on the very end of the left-hand side of the pole Assuming the daredevil applies upward forces with the left and right hands in a direction...
In a study of the
biomechanics of the tug-of-war, a 2.0-m-tall, 80.0-kg competitor in
the middle of the line is considered to be a rigid body leaning
back at an angle of 30.0?
to the vertical. The competitor is pulling on a
rope that is held horizontal a distance of 1.5m from his feet (as
measured along the line of the body). At the moment shown in the
(Figure 1) , the man is stationary and the tension in the...
(III) A uniform rod AB of length 5.0 m and mass M = 3.8 kg is hinged at A and held in equilibrium by a light cord, as shown in Fig. 9-67. A load W = 22 N hangs from the rod at a distance d so that the tension in the cord is 85 N. (a) Draw a free-body diagram for the rod. (b) Determine the vertical and horizontal forces on the rod exerted by the hinge. (c) Determine...
Rotational Dynamics Assignment (200 Points) • Due Friday, July 31 at 5:00 pm Equations are in a separate document entitled “Equations for Rotational Dynamics Assignment” • Moments of inertia formulas are provided on the last page of this document • Show all of your work when solving equations. It is not sufficient to merely have a correct numerical answer. You need to have used legitimate equations and algebra. You also need to have correctly used the data. • Units must...
