Torque Related Question: Explain how the derivative is found. mas (Height (h) and angle (a) are held constant) dan i. Write an expression for the magnitude of the torque exerted by the hanging mass about the rotation axis (pivot point), using r1, ml, a, and g. ri: the distance from the pivot to the hanging mass m1: the mass of the hanging object a: the angle between the rigid object and the floor g: the acceleration due to gravity üi. Write an expression for the magnitude of the torque exerted by the rigid object about the rotation axis (pivot point), using r2, m2, a, and g. r2: the distance between the pivot and the center of mass of the rigid object m2: the mass of the rigid object a: the angle between the rigid object and the floor g: the acceleration due to gravity. Write an expression for the magnitude of the force meter t about the rotation axis (pivot point), using r3, F, and q. r3: the distance between the pivot and the attachment of the force meter F: the force measured by the force meter 2: the angle between the rigid object and the force meter. iv. Let F90 be the force measured at 90°. Derive an equation for F90/F as a function of a.
