A balance and torque experiment is conducted with an UN-balanced ruler.
Length of the ruler: 1 m
Mass of the ruler: 193 g
The pivot is at the 35-cm mark.
A 46-g mass is located at the 82-cm mark of the ruler.
We want to balance the ruler by placing another mass at the 19-cm mark.
What should be magnitude of this additional mass?
Homework Answers
Balancing the torque about the pivot point,
M x (35 - 19) = 193(50 - 35) + 46(82 - 35)
M x 16 = 2895 + 2162
M = 316.06 g

Let's consider a variation of Experiment 2 where in- stead of the system being balanced by hanging a mass on the stick, we have the system lean against a frictionless wall (at a 30° angle relative to the hor- izontal), like a ladder except supported vertically and horizontally by an axle rather than the floor. To begin analyzing this system, label the perpendic- ular distance from the axis of rotation (chosen as the pivot point for simplicity) to the...

1.)In the static equilibrium experiment, a student placed the 107 g mass (including the hanger mass) at position of 6.6 cm from the fulcrum. Then, placed a 52 g mass (including the hanger mass) on the right side of the fulcrum and adjusted the position until balance is achieved. Calculate the torque (magnitude only) caused by the 107 g mass. (g = 9.80 m/s2) 2.)In the static equilibrium experiment, a student placed the 105 g mass (including the hanger mass)...
