Wednesday, April 10, 2019 ue and balance Torque and balance problems LAB193_07 A balance and torque experiment is conducted with a balanced ruler (that is, the pivot point is in the middle). Length of the ruler. 1 m Weight of the ruler. 3 N Mass 1: 245 g. This mass is placed at the 2-cm mark on the ruler Mass 2: 40 g. Where should this mass be placed to balance the ruler? Answer Check A balance and torque experiment is conducted with a balanced ruler (that is, the pivot point is in the middle) A balance and torque experiment is conducted with a balanced ruler (that is, the pivot point is in the middle) Length of the ruler. 1 m Weight of the ruler 8 N Mass 1: 234 g. This mass is placed at the 32-cm mark on the ruler The second mass is to be placed at the 94-cm mark on the ruler What should be the magnitude of the second mass? Answer Check A balance and torque experiment is conducted with a balanced ruler (that is, the pivot point is in the middle). Length of the ruler. 1 m Mass of the ruler. 800 g Two masses are placed on the ruler. You need to find where to place the third mass to balance it. Mass 1: 233 g. This mass is placed at the 23-cm mark on the ruler. Mass 2: 120 g. This mass is placed at the 79 cm mark of the same ruler. At what mark should a third, 374-g mass be placed to restore the balance? Answer Check A balance and torque experiment is conducted with a balanced ruler (that is, the pivot point is in the middle) Length of the ruler. 1 m 0 Mass of the ruler. 700 g Weight 1: 2.4 N. This weight is placed at the 20-cm mark on the ruler. Weight 2: 7 N. This weight is placed at the 54-cm mark on the ruler. We want to balance the ruler by placing a weight at the 87-cm mark What should the magnitude of this weight? Answer Check A balance and torque experiment is conducted with a balanced ruler (that is, the pivot point is in the middle) Length of the ruler. 1 m ete Mass of the ruler 650 g Weight 1: 4N. This weight is placed at the 9-cm mark on the ruler Weight 2: 4N. This weight is placed at the 56-cm mark on the ruler. We want to balance the ruler by supporting it with a spring scale at the 5-cm mark What reading should we expect on the spring scale? of 1.00 uestion Answer. Check A balance and torque experiment is conducted with an UN-balanced ruler Length of the ruler. 1 m Mass of the ruler 296 g The pivot is at the 25-cm mark. We want to balance the ruler by placing a 3-N weight at the appropriate location At what cm mark on the ruler should this weight be placed Answer. Check A balance and torque experiment is conducted with an UN-balanced ruler. Length of the ruler. 1 m Mass of the ruler. 272 g The pivot is at the 68-cm mark. We want to balance the ruler by placing a weight at the 86-cm mark. What is the magnitude of the weight that should be placed there? Answer Check A balance and torque experiment is conducted with an UN-balanced ruler. Length of the ruler. 1 m Mass of the ruler. 90 g The pivot is at the 74-cm mark. We want to balance the ruler by supporting it with a spring scale at the 47-cm mark. What do we theoretically expect the reading on the spring scale to be? Answer Check A balance and torque experiment is conducted with an UN-balanced ruler. Length of the ruler 1 m Mass of the ruler 229 g The pivot is at the 32-cm mark. A 91-g mass is located at the 79-cm mark of the ruler. We want to balance the ruler by placing another mass at the 15-cm mark. What should be magnitude of this additional mass? Answer Check A balance and torque experiment is conducted with an UN-balanced ruler. Length of the ruler. 1 m Mass of the ruler 272g The pivot is at the 60-cm mark. A 50-g mass is located at the 80-cm mark of the ruler. We want to balance the ruler by placing a 288-g mass somewhere on the ruler. At which mark on the ruler should we place the 288-g mass?
