Questions and Answers
What is the point of an object at which the weight is evenly dispersed and all sides are in balance called?
What is the point of an object at which the weight is evenly dispersed and all sides are in balance called?
- Load
- Fulcrum
- Effort
- Center of gravity (correct)
What is the formula for mechanical advantage of a lever?
What is the formula for mechanical advantage of a lever?
- $MA = Force hinspace Arm hinspace Length + Resistance hinspace Arm hinspace Length$
- $MA = Force hinspace Arm hinspace Length \times Resistance hinspace Arm hinspace Length$
- $MA = Force hinspace Arm hinspace Length - Resistance hinspace Arm hinspace Length$
- $MA = \frac{Force hinspace Arm hinspace Length}{Resistance hinspace Arm hinspace Length}$ (correct)
What determines the classification of levers as first-, second-, or third-class?
What determines the classification of levers as first-, second-, or third-class?
- The length of the lever
- The material of the lever
- The relative positions of the axis, weight, and force to each other (correct)
- The weight alone
