Center of gravity PHYSICS question!?! balance Please help me figure it out!?
You have to cook the Thanksgiving turkey. Free wine label. Betty Crocker ___ told him many hours to cook a turkey, 8 pounds, ___ hours for the turkey of 10 pounds, and so on and so forth. But you do not have a scale. Let's say you take a two by four (piece of wood) and the balance on the arm of the sofa. Next, take a brand new, unopened 5 [lb] bag sugar and place 74 [cm] on the arm of the sofa. Sugar / board / balances system turkey when the turkey is placed 37 [cm] on the arm of the sofa. How much turkey weighs?
The weight of Turkey = w Let's calculate the moments along the soft arm. Torque has a magnitude of W = W * 37 cm wide bag of sugar weight has magnitude = £ 5 * 74 cm The two moments are in the opposite direction. There was no balance. Therefore, the total torque = 0 Consequently, w * 37 cm = 5 lbs * 74 cm or W = 5 * 74/37 pounds = 5 * Ans 2 pounds = 10 pounds: 10 pounds
