Torque - Mass on Plank with String

The video tutorial explains a physics problem involving a mass resting on a wooden plank supported by a string. It covers the setup, free body diagram, forces, torque, and static friction. The tutorial demonstrates solving for the tension in the string and the normal force from the wall, concluding with a practical demonstration and discussion of results.

What is the significance of the angle between the string and the plank?

Describe how the force normal from the wall is calculated.

What were the measured forces during the demonstration, and how do they compare to the calculated values?
