- A meter stick is found to balance at the 49.7-cm mark whenplaced on a fulcrum. When a 50.0-gram mass is attached atthe 10.0-cm mark, the fulcrum must be moved to the 39.2-cmmark for balance. What is the mass of the meter stick?Two children with masses of 24 kg and 34 kg are sitting on a balanced seesaw. If the heavier child is sitting O.8 m from the center, at what distance from the center is the lighter child sitting? Your answer4. A meter stick has a pivot that is located at (35 cm). On this meter stick weplace 200 g @ 20 cm, 200 g @ 25 cm, 350 g @70 cm and 100 g @80 cm.The meter stick has a mass of 150 g. a. How much mass needs to be placed at 55 cm in order to balance themeter stick.__________________________ b. Where will you put 500 g in order to balance the meterstick?___________________________________ If you could clearly circle the answers I need, that would be great! Thanks!
- A weight of 16 N is located at a distance of 16 cm from the fulcrum of a simple balance beam. At what distance from the fulcrum should a weight of 18 N be placed on the opposite side in order to balance the system? cm?In the figure, a 60 kgkg man walks out on a 14 kgkg beam that rests on, but is not attached to, two supports.(Figure 1) When the beam just starts to tip, what is the force exerted on the beam by the right support? Express your answer to two significant figures and include the appropriate units.The outstretched handsand arms of a figure skater preparingfor a spin can be considered aslender rod pivoting about an axisthrough its center (Fig. ).When the skater’s hands and armsare brought in and wrapped aroundhis body to execute the spin, thehands and arms can be considereda thin-walled, hollow cylinder. Hishands and arms have a combinedmass of 8.0 kg. When outstretched, they span 1.8 m; when wrapped,they form a cylinder of radius 25 cm. The moment of inertia aboutthe rotation axis of the remainder of his body is constant and equal to0.40 kg . m2. If his original angular speed is 0.40 rev/s, what is his finalangular speed?
- 3. A meter stick has a pivot that is located in the middle (50 cm). On thismeter stick we place 150 g @ 32 cm, 300 g @ 45 cm, 100 g @80 cm and300 g @80 cm.a. How much mass needs to be placed at 55 cm in order to balance themeter stick.__________________________ b. Where will you put 500 g in order to balance the meterstick?___________________________________ If you could clearly circle the answers I need that would be great! Thanks!A meter stick is found to balance at the 49.7-cm mark when placed on a fulcrum. When a 58.0-gram mass is attached at the 22.5-cm mark, the fulcrum must be moved to the 39.2-cm mark for balance. What is the mass of the meter stick?10kg rigid beam that is 3mlong is supported at each end. An8kg block is placed 2m fromsupport 1. How much upward forcedoes each support provide to ensurezero acceleration and zero torque?Note, if an object is not rotating, itis not rotating about every axis.
- 2.15 A large wood beam weighing 800 N is supported by two posts as shown. If an unthinking man weighing 700 N were to walk on the overhang portion of the beam, how far can he go from point A before the beam tips over? (Assume the beam is resting on the two supports with no physical connection.) 2m WMAN 100N A ImA box of mass 5 ?? is placed 1.5 ? at the end of a plank pivoted in the middle. Anotherbox of mass 15 ?? is placed somewhere to balance the system.a. Find the weight of the two crates. [4 marks]b. Find the location of the other box in the balanced system. [3 marks]c. The first box is replaced with a box of weight 17 0 ? at 0.7 ? from the pivot.What is the new location of box two to balance the system?In order to balance a meterstick at the 27 cm mark, how much weight would you need to hang at the 10 cm mark? Assume the stick weighs 200 g and its center of mass is at 50 cm.
