TL;DR

This video explains how to determine the law of a machine based on given effort and load values.

Transcript

hello friends in this video i will take the problem in which we will be developing the law of machine here is a question an effort of 800 newton is required to lift a load of 10 kilo newton on this same machine an effort of 1400 newton lifts a load of 22 kilo newton full stop find the law of machine so here the question is to determine the law of m...

Key Insights

• 👮‍♂️ The law of machine is represented by the equation p = mw + c, where p is effort, m is a constant, w is load, and c is another constant.
• 👮‍♂️ By solving two equations using given effort and load values, the constants m and c can be determined, allowing for the determination of the law of the machine.
• 👮 The law of machine can be used to calculate effort when load is known, or to find load when effort is known.
• 😀 In this example, the constants m and c are found to be 0.05 and 300, respectively.

Questions & Answers

Q: What is the formula for the law of machine?

The formula for the law of machine is p = mw + c, where p is effort, m is a constant, w is load, and c is another constant.

Q: How are the constants m and c determined?

The constants m and c can be determined by solving two equations using the given effort and load values and applying basic algebraic operations.

Q: What can be calculated using the law of machine?

Using the law of machine, if the value of load is given, the effort can be calculated. Similarly, if the effort is given, the load can be found out.

Q: What is the law of machine in this specific example?

In this example, the law of machine is given by p = 0.05w + 300, where p is effort in newtons and w is load in kilonewtons.

Summary & Key Takeaways
