Homework Statement
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?
Homework Equations
T is Torque, F is Force
T = 0
F = 0
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.
