Title:Static Equilibrium - Tension, Torque, Lever, Beam, & Ladder Problem - Physics

This physics video tutorial explains the concept of static equilibrium - translational & rotational equilibrium where everything is at rest and there's no motion. This video contains plenty of examples and practice problems. Static Equilibrium: Elasticity and Hooke's Law: Tensile Stress: Elastic Modulus: Bulk Modulus: ___________________________ Volume Unit Conversion: Specific Gravity & Density of Mixtures: Will It Sink or Float? Intro to Pressure & Fluids: Atmospheric Pressure Problems: ____________________________ The Gallon Crusher: Absolute Pressure Vs Gauge Pressure: Water Pressure Vs Gauge Pressure: Full-Length Videos and Worksheets: Physics PDF Worksheets: Here is a list of topics: 1. Static Equilibrium Problems 2. Balancing a Seesaw - Lever Problem - Using Forces and Torques 3. Torque equals force times lever arm / moment arm 4. Positive and Negative Torques - Clockwise vs Counterclockwise rotation 5. Hanging Sign Tension Problem - Finding the tension in the two cables at two different angles 6. Hanging sign attached to a beam problem - how to calculate the horizontal and vertical components of the force exerted by the hinge and pivot point 7. Hanging sign attached to a beam at an angle - determining the tension force in the cable 8.
