The flywheel is subjected to a torque of $M=75 \mathrm{N} \cdot \mathrm{m} .$ Determine the horizontal compressive force $F$ and plot the result of $F$ (ordinate) versus the equilibrium position $\theta(\text { abscissa })$ for $0^{\circ} \leq \theta \leq 180^{\circ}$

Key Concepts

Graphical Analysis

Graphical analysis involves plotting the calculated or functionally derived relationships (such as force versus angle) to visualize how a variable changes with respect to another. In mechanical systems, plotting functions such as compressive force against equilibrium position can help in understanding system behavior over a range of operating conditions.

Moment Arm

The moment arm is the perpendicular distance from the axis of rotation to the line of action of a force. It is an essential concept when linking forces with torques, as a force applied further from the pivot produces a larger torque. This concept helps determine how variations in system geometry or angle affect the system's response.

Static Equilibrium

Static equilibrium refers to a condition where an object is at rest or moving with constant velocity, meaning the net force and net torque acting on the object are zero. In problems involving mechanical systems, ensuring that all forces and moments balance is essential for solving for unknown forces or reactions.

Torque

Torque is a measure of the tendency of a force to rotate an object about an axis. It is calculated as the product of the applied force and the perpendicular distance from the axis of rotation to the line of action of the force. Understanding torque is fundamental in analyzing rotating systems and determining the forces needed to achieve or resist rotational motion.

Force Decomposition

Force decomposition involves breaking a resultant force into its components along specified axes, such as horizontal and vertical directions. This is crucial in mechanical analyses where the effect of a force depends on its direction, and it allows for applying equilibrium conditions separately in different directions.
