Question
A meter stick is supported by a knife-edge at the 50-cm mark. You hang masses of 0.40 kg and 0.60 kg from the 20-cm and 80-cm marks, respectively. Where should you hang a third mass of 0.30 kg to keep the stick balanced?

- A cargo ship has been badly loaded and is dangerously down at the stern. Fortunately, there is a massless crane based on the ship near its bow. The captain decides to balance the ship by using the crane to lift a container from near the stern, move it horizontally forwards, and lower it onto the bow. When does the ship's angle begin to improve?arrow_forwardWhen you lift an object by moving only your forearm, the main lifting muscle in your arm is the biceps. Suppose the mass of a forearm with hand is 1.60 kg. If the biceps is connected to the forearm a distance of 2.1 cm from the elbow, how much force must the biceps exert to hold a 35 N ball at the end of the forearm at distance of 36.0 cm from the elbow, with the forearm parallel to the floor, in Newtons? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.arrow_forwardA meter stick is hanging from the ceiling at the 50 cm marker, perfectly in balance..

- Consider a method for measuring the mass of a person’s arm in anatomical studies. The subject lies on her back, extends her relaxed arm to the side and two scales are placed below the arm. One is placed under the elbow and the other under the back of her hand. Construct a problem in which you calculate the mass of the arm and find its center of mass based on the scale readings and the distances of the scales from the shoulder joint. You must include a free body diagram of the arm to direct the analysis. Consider changing the position of the scale under the hand to provide more information, if needed. You may wish to consult references to obtain reasonable mass values.arrow_forwardA sandwich board advertising sign is constructed as shown in Figure 5.39. Its mass is 7.40 kg.

- 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.arrow_forwardTwo 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)arrow_forwardA 10 m long board has a mass of 7 kg.
