1. The problem statement, all variables and given/known data To make larger pictures, an enlarger can be moved to the edge of a table so that the image is projected onto the floor, as shown. mass of bass = 2.0 kg mass of support = 2.0 kg mass of enlarger = 6.0 kg a) What is the minimum mass that needs to be added on the base at point A to keep the enlarger from tipping off the table? b) With this mass in place, what will be the reaction (normal) force at B? 2. Relevant equations T is Torque, F is Force T = 0 F = 0 3. The attempt at a solution base (b) support (s) enlarger (e) if A is the pivot and counterclockwise is positive: -Tb - Ts - Te = 0 did i set the question up correctly? i don't know if A is the pivot point, or if i've got the negatives right. this torque business is difficult.
