Q1. What is angle of projection
Ans. 
Angle of projection is the angle at which an object is projected from the horizontal.
• Angle of projection is measured from the horizontal axis.

• It determines the trajectory of the object being projected.

• A smaller angle of projection results in a shorter range but higher height, while a larger angle results in a longer range but lower height.

• For example, in sports like basketball, the angle of projection of a shot can aff

Q2. Difference between 1st angle,2nd 3rd 4th angle projection
Ans. 
1st, 2nd, 3rd, and 4th angle projections are different methods of representing a 3D object on a 2D plane in engineering drawings.
• 1st angle projection: Commonly used in Europe and Asia, where the object is placed in the first quadrant.

• 2nd angle projection: Commonly used in North America, where the object is placed in the fourth quadrant.

• 3rd angle projection: Commonly used in Australia and the UK, where the object is pla...read more

Q2. What is the slump for pumped concrete in a construction site? Ans. 80-100mm
Ans. 
The slump for pumped concrete in a construction site is typically 80-100mm.
• Slump refers to the measure of consistency or workability of concrete.

• Pumped concrete is used when concrete needs to be transported through pipes or hoses.

• A slump of 80-100mm is considered suitable for pumped concrete as it allows for easy flow and placement.

• If the slump is too low, the concrete may be difficult to pump, while a high slump may l...read more
