Cummins Generator Technologies Junior Design Engineer Interview Questions and Answers

Leaping length is the distance between two consecutive supports of a bridge or a beam.

• Leaping length is also known as span length.

• It is an important factor in the design of bridges and beams.

• The leaping length determines the maximum load that the structure can bear.

• For example, a bridge with a leaping length of 50 meters can bear heavier loads than a bridge with a leaping length of 30 meters.

UTM stands for Universal Transverse Mercator, a coordinate system used to locate positions on the Earth's surface.

• UTM divides the Earth into 60 zones, each 6 degrees of longitude wide.

• It uses a grid system to give a unique location to every point on the Earth's surface.

• UTM coordinates are given in meters, making it easy to measure distances and areas.

• It is commonly used in mapping, surveying, and navigation application...read more

The 20 in M20 refers to the compressive strength of concrete in megapascals after 28 days of curing.

• M20 is a mix of concrete with a compressive strength of 20 MPa after 28 days of curing.

• The compressive strength of concrete is the maximum load it can bear before crushing.

• The strength of concrete depends on the ratio of cement, sand, and aggregate used in the mix.

• Other grades of concrete include M10, M15, M25, M30, etc....read more

Lift is a vertical transportation system that moves people or goods between floors or levels of a building.

• Lifts are commonly used in high-rise buildings.

• They operate using a motorized system that moves a cab or platform up and down a shaft.

• Lifts can be hydraulic, traction, or pneumatic.

• They are equipped with safety features such as emergency brakes and backup power supplies.

• Lifts are regulated by safety codes and stan

Types of lift include hydraulic, traction, and pneumatic lifts.

• Hydraulic lifts use fluid pressure to move the elevator car.

• Traction lifts use cables and a counterweight to move the car.

• Pneumatic lifts use air pressure to move the car.

• Other types of lifts include scissor lifts, boom lifts, and platform lifts.

There are various types of elevators such as hydraulic, traction, pneumatic, residential, machine room-less, etc.

• Hydraulic elevators use a hydraulic piston to move the elevator car.

• Traction elevators use cables and counterweights to move the car.

• Pneumatic elevators use air pressure to move the car.

• Residential elevators are designed for private homes.

• Machine room-less elevators do not require a separate machine room.

• Fre...read more
