A $10000-\mathrm{N}$ shark is supported by a cable attached to a 4.00 $\mathrm{m}$ rod that can pivot at the base. Calculate the tension in the tie rope between the rod and the wall, assuming the tie rope is holding the system in the position shown in Figure $\mathrm{P} 12.43$ . Find the horizontal and vertical forces exerted on the base of the rod. Ignore the weight of the rod.

Key Concepts

Static Equilibrium

Static equilibrium means that the net force and the net moment (torque) acting on a system are zero. This condition is used to set up equations for both the forces and moments, which is essential for solving problems involving objects at rest or moving at constant velocity.

Free-Body Diagram

A free-body diagram is a simplified representation of the object that isolates it from its surroundings, showing all the external forces and moments acting on it. This visual tool is crucial for understanding the force distribution and applying equilibrium equations.

Torque (Moment) Balance

Torque, or moment of a force, is the product of the force and its perpendicular distance from a pivot point. The balance of torques (ensuring that the sum of clockwise torques equals the sum of anticlockwise torques) is key to solving for unknown forces in systems with rotating elements.

Reaction Forces at a Pivot

Reaction forces at a pivot are the forces exerted by a support that prevent translation or rotation of the system. These forces, often having both horizontal and vertical components, can be determined by applying the equilibrium conditions in the respective directions.

Tension Force Analysis

Tension force analysis involves determining the force transmitted through a rope, cable, or tie. In static systems, the magnitude and direction of the tension are found by decomposing the force components and ensuring they satisfy the conditions for equilibrium.
