Q1. A beam is hinged on both ends and a load is applied in between what are the additional thing we can do to reduce the deformation
Ans. 
To reduce deformation in a beam hinged on both ends with a load applied in between, additional measures can be taken.
• Increase the beam's cross-sectional area to improve stiffness

• Use materials with higher modulus of elasticity

• Add support columns or braces to reduce bending

• Distribute the load more evenly along the beam

• Reduce the span length of the beam for better support

Q2. Types of gears and name them
Ans. 
Types of gears include spur gears, helical gears, bevel gears, worm gears, and rack and pinion gears.
• Spur gears have straight teeth and are the most common type of gear.

• Helical gears have angled teeth for smoother and quieter operation.

• Bevel gears have cone-shaped teeth and are used to change the direction of rotation.

• Worm gears have a screw-like appearance and provide high gear reduction ratios.

• Rack and pinion gears c

Q1. What is relative humidity
Ans. 
Relative humidity is the amount of water vapor present in the air compared to the maximum amount the air can hold at a specific temperature.
• Relative humidity is expressed as a percentage.

• It is an important factor in weather forecasting and climate studies.

• High relative humidity can make the air feel warmer than it actually is, while low relative humidity can make the air feel cooler.

• For example, if the relative humidit...read more

Q2. Types of pumps?
Ans. 
Types of pumps include centrifugal pumps, positive displacement pumps, and axial flow pumps.
• Centrifugal pumps use a rotating impeller to increase the pressure of a fluid.

• Positive displacement pumps move fluid by trapping a fixed amount and forcing it through the discharge.

• Axial flow pumps move fluid parallel to the pump shaft.

• Examples: Centrifugal pump - used in HVAC systems, Positive displacement pump - used in hydrau...read more

Q3. Extractive distillation means?
Ans. 
Extractive distillation is a process used to separate components of a liquid mixture by adding a solvent that preferentially removes one component.
• Involves adding a solvent to the mixture to enhance separation

• Solvent selectively removes one component from the mixture

• Used when normal distillation is not effective in separating components
