Determine the absolute value of the net muscle moment at the left shoulder as the worker pulls straight downward on the handle with his left hand with a force of 68 N. The horizontal distance from the shoulder to his hand is 48 cm, the vertical distance from the shoulder to his hand is 28 cm, the mass of his left upper extremity (upper arm + forearm + hand) is 8 kg, and the combined COM of his left upper extremity, as measured from the shoulder, is located 17 cm in the negative x-direction (to the left in the figure), and 9 cm in the positive y-direction (upward in the figure). Round your answer to the nearest whole number.

A hand exerts a force of 125 N on a scale at 30 cm from the joint center at the elbow. If the triceps attaches to the ulna at a 90° angle and at a distance of 3.5 cm from the elbow joint center, and if the weight of the forearm and hand is 45 N with the hand/ forearm CG located 15 cm from the elbow joint center, how much force is being exerted by the triceps?
In a car, the engine running at 3000 r.p.m. has a crank radius of 15 cm and connecting rod length of 0.5 m. The reciprocating part in each cylinder is 4 kg. If the cylinders are numbered 1 to 6 in sequence from one end, the cranks appear at intervals of 30° in an end view in the order 1-5-3-4-2-6.

A man who weighs 180 lbs.is riding in an elevator. Find the force exerted on the man by the floor of the elevator under the following conditions: (a) The elevator is accelerating upward at 12 ft/sec2. (b) The elevator is accelerating downward at 12 ft/sec2. (c) The elevator is accelerating downward at 32 ft/sec2. Have we made any restrictions on the directions of the velocity in parts (a), (b), and/or (c)? If so, what?

=↑ -7----- mg Sw mg 2. A drone of mass m (shown above) moves with a horizontal velocity v and is propelled by a thrust force ft produced from its propellers. To move, it tilts itself by an angle 0, which causes the thrust force ft to take on a component in the horizontal direction. This forward-directed force is indicated by ff in the diagram above. The drone is also subject to an aerodynamic drag force fa that acts in a horizontal direction and is proportional to forward velocity according to fa= -bv (regardless of 0). (a) Assuming ft acts along the inclined axis of the body, find ff as a function of the tilt angle and ft. (b) Find the necessary thrust ft needed to ensure that lift is balanced by gravity so that the drone does not move vertically. That is, find ft such that its vertical component as shown is equal to mg. Your answer will be a function of 0, g, and m. (c) Give the the small-angle approximations of these two functions when ≈ 0. (d) Suppose the drone has a mass m = 1 kg…
