Q: Two men attempt to pull a box in the diagram below: What is the resultant force in Newtons ( N ) exerted on the box? A: This is a classic question involving a 3-4-5 right triangle. Trigonometry and the Pythagorean Theorem enable us to solve the problem using the numbers 3, 4, and 5.Continue reading “FORCE AND ACCELERATION: 3-4-5 Right-Triangle Mathematics”

FORCE AND ACCELERATION: Mechanical Advantage and Tension Within Pulley Systems
The law of conservation of energy states that the total energy of an isolated system remains constant. The SI unit of energy is the joule ( J ), and it’s base-unit composition is kg*m2/s2. Energy is the currency needed to perform work, and work is performed upon an object when an applied force moves itContinue reading “FORCE AND ACCELERATION: Mechanical Advantage and Tension Within Pulley Systems”
