Jacobs Engineering Group Civil Engineer Interview Questions and Answers for Experienced

The least count of staff reading is the smallest measurement that can be read and recorded using the staff.

• The least count is determined by the smallest division on the staff scale.

• It is usually expressed in millimeters or centimeters.

• For example, if the smallest division on the staff scale is 1 mm, then the least count is 1 mm.

• The least count is important in accurately measuring and recording distances in civil engine

Tension is a force that pulls or stretches an object.

• Tension is a type of mechanical stress that occurs when an object is pulled or stretched.

• It is a force that acts in the opposite direction of compression.

• Tension is commonly seen in structures like bridges and cables.

• Examples of tension include a rope being pulled taut or a rubber band being stretched.

Compression is the action of applying pressure to reduce the size or volume of an object or material.

• Compression is a force that squeezes or presses an object or material together.

• It is commonly used in civil engineering to test the strength of materials like concrete or soil.

• Compression can cause materials to deform or break if the force applied is too great.

• Examples of compression include the weight of a building pre...read more

Workability of concrete refers to its ease of mixing, placing, and compacting.

• Workability is an important property of concrete as it affects its strength, durability, and overall performance.

• It is influenced by factors such as water content, aggregate size and shape, cement content, and admixtures.

• Concrete with good workability is easier to handle, transport, and finish.

• Workability can be measured using tests like slum...read more

Admixtures are substances added to concrete to enhance its properties or performance.

• Admixtures can be classified into different types based on their purpose, such as water-reducing admixtures, air-entraining admixtures, accelerating admixtures, retarding admixtures, and superplasticizers.

• Water-reducing admixtures reduce the amount of water needed in the concrete mix, improving its workability and strength.

• Air-entraini...read more

A tilting mixer is used in construction projects to mix concrete or other materials.

• Tilting mixers are commonly used in construction sites to mix concrete for building foundations, walls, and floors.

• They are also used in road construction projects to mix asphalt and other paving materials.

• Tilting mixers are versatile and can be used for both small and large-scale construction projects.

• They are designed to tilt and pour...read more

The weight of a 10 mm diameter bar depends on the material it is made of.

• The weight can be calculated using the formula: weight = volume × density

• The volume of a cylindrical bar can be calculated using the formula: volume = π × (diameter/2)^2 × length

• The density of the material can be obtained from reference tables or material specifications

• For example, the weight of a 10 mm diameter steel bar with a length of 1 meter ...read more
