For a meter stick of mass 147.89 g, it is found that its weight can be balanced by hanging a 183.99 g mass at the 95.00 cm mark.  Where does the center of the weight of the meter stick locate on the meter stick? Enter the number in cm unit.

A taho vendor carries a 1.5 m long light plank over his shoulder. At the ends of the plank are two buckets weighing 40 N and 60 N respectively. (a) Find the value of force F exerted by his shoulder. Neglect the weight of the plank. ( b) Where should he support the plank for it to be balanced horizontally

A new art exhibit featuring mobile works is going up in the Holland, MI, area. One piece is shown in the figure. The 140-N uniform beam is pinned to the ground by a pivot. The beam is supported by a cable (attached to the center of the beam) to allow for each of the shoes to hang freely. Each individual shoe has a weight of 9.5-N. 1.If one shoe is attached two-fifths of the way up the beam and another shoe is attached and three-fifths of the way up the beam, with θc = 19.5° and θb = 33.5° as shown in the figure, what is the tension in the cable, in newtons?

Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the door. One child pushes with a force of 12.5 N at a distance of 0.750 m from the hinges, and the second child pushes at a distance of 0.550 m. What force must the second child exert to keep the door from moving? (assume friction is negligible)

A 68 kg man is in the prone position while during pushups. His feet and hands are 95 cm and 42 cm away respectively from his center of mass. What is the normal force exerted by on each (a) hand and (b) foot?

The forearm shown below is positioned at an angle with respect to the upper arm, and a 5.6 kg mass is held in the hand. The total mass of the forearm and hand is 2.1 kg, and their center of mass is 16.1 cm from the elbow. (Assume the biceps muscle exerts a force on the forearm that acts vertically.) 5.6 kg B 37.5 cm 4.0 cm (a) What is the magnitude of the force (in N) that the biceps muscle exerts on the forearm for 0-60%7 N (b) What is the magnitude of the force on the elbow joint (in N) for the same angle? N (c) How do these forces depend on the angle 07 The force that the biceps muscle exerts increases and the force on the elbow joint decreases as increases. They both decrease as @ increases. They both increase as increases. They do not depend on 0. The force that the biceps muscle exerts decreases and the force on the elbow joint increases as increases.

An athlete holds a 34.0 N pole in equilibrium by exerting an upward force U with her left hand and a downward force D with her right hand as shown. Point C is the center of gravity of the pole. (Let L₁ 2.25 m, 42 1.35 m, and L3 = = = 0.900 m. Due to the nature of this problem, do not use rounded intermediate values-including answers submitted in WebAssign-in your calculations.) L3 L2 B D g (a) What is the magnitude of U (in N)? N (b) What is the magnitude of D (in N)? N
