Technico Industries DET Interview Questions, Process, and Tips

Torque is a measure of the twisting force applied to an object.

• Torque is the product of force and the perpendicular distance from the axis of rotation.

• It causes objects to rotate around an axis.

• Torque is measured in units of force multiplied by distance, such as Newton-meters or foot-pounds.

• Examples of torque include turning a doorknob, tightening a bolt with a wrench, or pedaling a bicycle.

Two-stroke and four-stroke engines differ in their operation and design.

• Two-stroke engines complete a power cycle in two strokes of the piston, while four-stroke engines complete it in four strokes.

• Two-stroke engines have a simpler design and are lighter, but they are less fuel-efficient and produce more pollution.

• Four-stroke engines are more complex but offer better fuel efficiency and lower emissions.

There are several types of welding techniques used in various industries.

• Arc welding: Uses an electric arc to create heat and join metals.

• MIG welding: Uses a wire electrode and a shielding gas to create a weld.

• TIG welding: Uses a tungsten electrode and a shielding gas to create a precise and high-quality weld.

• Spot welding: Joins two or more metal sheets by applying pressure and heat at specific points.

• Flux-cored arc we...read more

There are various types of steel used in different applications.

• Carbon steel: contains carbon as the main alloying element

• Stainless steel: contains chromium for corrosion resistance

• Tool steel: used for making tools and dies

• Alloy steel: contains additional alloying elements for specific properties

• High-speed steel: used for cutting tools at high speeds
