Questions & Answers

Q: How is effort lost in friction calculated?

Effort lost in friction is calculated by subtracting the ideal effort from the actual effort using the formula: effort loss in friction = actual effort - ideal effort.

Q: What is the formula for ideal effort?

The formula for ideal effort is calculated using the formula: ideal effort = load / velocity ratio, where the velocity ratio is the ratio of load to effort.

Q: How is load loss in friction calculated?

Load loss in friction is calculated by subtracting the actual load from the ideal load using the formula: load loss in friction = (actual effort x velocity ratio) - actual load.

Q: What is the formula for ideal load?

The formula for ideal load is calculated using the formula: ideal load = effort x velocity ratio, where the velocity ratio is the ratio of load to effort.

Summary & Key Takeaways

• The problem involves lifting a load of 100 Newton with an effort of 8 Newton at an efficiency of 62.5%.

• The solution involves calculating the effort lost in friction using the formula: actual effort minus ideal effort.

• The load loss in friction is calculated by subtracting the actual load from the ideal load.
