The purpose of this experiment is to understand the concepts of torque and it’s relation to rotational equilibrium. We define Torque as the measure of the turning effect of an applied force on an object. It’s equation is denoted as: =dF where d is the perpendicular distance from the pivot point to the line of the action of the force , and F is the applied force. We also know that the perpendicular distance is the radius (r) multiplied by the sine of the angle in between the radius and force applied denoted as the equation d=r(sinθ) Since we are doing an experiement with more than one Torque force applied we will use the equation ΣΤ=F 2 d 2 -F 1 d 1 Knowing that ΣΤ= 0 However, if we were had an object that has static equilibrium we will use three different equations for all of the forces such as in Part A,B,C: For part A: ΣΤ =(m1+mh)gx 1 -(m2+mh)gx 2 -(m3+mh)gx 3 =0 For part B: ΣΤ =(m1+mh)gx 1 -(m2+mh)gx 2 =0 For pat C: ΣΤ =-(m1+mh)gx 1+ (m2+mh)gx 2+ (m3+mh)gx 3
