What is the mechanical advantage of a lever defined as?Question 6Select one:a.Effort/loadb.Load/fulcrumc.Fulcrum/effortd.Load/effort

Break Down the Problem

1. Identify the definitions involved: mechanical advantage of a lever.
2. Understand the relationship between the effort, load, and fulcrum in a lever.

Relevant Concepts

• Mechanical Advantage (MA) of a lever is defined as the ratio of the load force to the effort force applied to the lever. The formula for mechanical advantage can be expressed as: $MA = \frac{\text{Load}}{\text{Effort}}$

Analysis and Detail

1. Effort: The force applied to the lever.
2. Load: The weight or resistance that is moved by the lever.
3. Fulcrum: The pivot point around which the lever rotates.
4. The mechanical advantage of a lever determines how much the lever amplifies the input force.

From the formula, it's evident that the correct expression relates load and effort.

Verify and Summarize

Confirming that the definition aligns with the expected outcome: the mechanical advantage is derived from the load divided by the effort.

Final Answer

The correct answer is: d. Load/effort
