10 Most Asked Questions From Machine Design

1. What are the basic principles of machine design?

The basic principles of machine design include the strength of materials, fatigue analysis, machining, and assembly.

2. How do engineers design machines?

Engineers design machines by first understanding the purpose of the machine and then determining the loads that the machine will experience. They then test different designs to see which one can best withstand the loads.

3. What are the main types of loads that machines experience?

The main types of loads that machines experience are static loads and dynamic loads.

4. How do engineers choose materials for machines?

Engineers choose materials for machines based on their strength, stiffness, hardness, and other properties.

5. How do engineers test machines?

Engineers test machines by subjecting them to various loads and then measuring the deflection, stress, or strain that the machine experiences.

6. What are the main types of bearings?

The main types of bearings are roller bearings and ball bearings.

7. What are the main types of gears?

The main types of gears are spur gears, helical gears, and bevel gears.

8. What is a belt drive?

A belt drive is a type of mechanical power transmission that uses belts and pulleys to transfer power from one shaft to another.

9. What is a chain drive?

A chain drive is a type of mechanical power transmission that uses chains and sprockets to transfer power from one shaft to another.

10. What is a cam?

A cam is a rotating or reciprocating part that is used to transfer motion to or from another part, typically via followers.
