Lab Report #4 Force Table Purpose: To learn how to resolve force vectors, and to balance multiple weights, and then to describe the forces acting upon those weights. Then add a set of vectors using three methods: the graphical, analytical and experimental to find the resultant vector. Theory: According to Newton’s second law, an object that is not accelerating has no net force. The method for vector addition can be done in multiple ways, for instance by finding the orthogonal components of each vector and adding them so that the components of the resultant vector R is related to the components of the individual vectors A, B, etc.. R x = A x + B x + N x R y = A y + B y + N y Where N, is the total number of forces action on the object. The magnitude of the resultant vector, R x 2 + R y 2 = R And then the angle can be calculated by the equation below, θ = ¿ R y R x tan ¿ Procedure: Place the bubble level on the force table to check if it is leveled, clamp the pulleys on the force table at specified angles and add the specified weight to each of them. Add the correct mass on the other pulley so that the central ring is in the center of the pin. Record the
