Introduction: When force causes an object to spin, torque is considered. There is an origin which causes the object to move at an arc on the axis. To find the magnitude of torque we us the equation torque equals (length between where the force is applied and origin) times the magnitude of the vector times sin (angle between the force vector and lever arm vector). It also just equals the force of the vector times the distance of the force vector to axis. The normal force would be the line from the axis point through the intersection of the vectors and whatever direction it goes or the opposite direction of the resultant. To find the direction we would use the formula tan^-1[fy/fx]. Results: Questions and Exercises: 1) a. the forces are equal on both sides of the pivot point b. It satisfied because if the vector sum of r1 and rc equals r2, and if the sum g the forces g these

Unformatted text preview: vectors equal zero, that results in the balance exerting no tilt or rotation about the axis. 2) a. yes. If the axis is at the origin point, then theres no torque present. Torque is only found when there is both a force and a vector that is perpendicular to the origin point are present. b. no Conclusion: The experiment teaches me how to accurately measure the forces and torques from unique angles using the force tables. It also shows how the conditions of equilibrium of an object can be met. I see how to calculate the torques of the forces when using various angles. The calculations for the results seemed simple since I got 90 degrees angles each time I connected the vectors....
