Design Engineer 1 Interview Questions and Answers

The theory of failure widely used in engineering is the Von Mises criterion due to its accuracy in predicting material failure under complex loading conditions.

• Von Mises criterion is widely used in engineering for predicting material failure under complex loading conditions

• It takes into account both normal and shear stresses to determine the equivalent stress that leads to failure

• Other theories like Maximum Principal Stress theory and Maximum Shear Stress theory are less accu...read more

Torque is the rotational force applied to an object, while power is the rate at which work is done. They are related but not interchangeable.

• Torque is a measure of rotational force applied to an object, while power is the rate at which work is done.

• Torque is calculated as force multiplied by distance, while power is calculated as work done divided by time.

• Torque is important in rotating machinery like engines and motors, while power is a measure of overall performance.

• They ar...read more

Torque can be transferred through various modes such as direct contact, gears, belts, chains, and shafts.

• Direct contact between two surfaces transferring torque through friction

• Gears transferring torque through meshing teeth

• Belts transferring torque through friction between belt and pulley

• Chains transferring torque through links engaging sprockets

• Shafts transferring torque through rotational force

Factor of Safety is a design parameter used to ensure the safety and reliability of a structure or component.

• Factor of Safety is the ratio of the maximum stress a material can withstand to the maximum stress it is subjected to in a given application.

• It is used to account for uncertainties in material properties, loading conditions, and other factors.

• A higher factor of safety indicates a more conservative design approach, while a lower factor of safety may be used for less cri...read more
