Q2. Types of braking system
Ans. 
Braking systems are used in vehicles to slow down or stop the vehicle by converting kinetic energy into heat energy.
• Mechanical braking system: uses friction to slow down the vehicle (e.g. drum brakes)

• Hydraulic braking system: uses fluid pressure to transfer force to the brake pads (e.g. disc brakes)

• Regenerative braking system: converts kinetic energy into electrical energy to recharge the battery (e.g. in hybrid or ele

Q1. Questions were asked regarding suspension geometries and calculations?
Add your answer
Q2. Explain about the different suspension geometries and explain how forces act on them
Ans. 
Suspension geometries include double wishbone, MacPherson strut, and multi-link, each experiencing different forces like compression, rebound, and lateral forces.
• Double wishbone suspension has two control arms that allow for independent control of camber and toe angles.

• MacPherson strut suspension uses a single control arm and a strut to support the wheel and handle vertical forces.

• Multi-link suspension uses multiple co...read more

Q1. What does the stress-strain graph of stainless steel look like?
Ans. 
Stress-strain graph of stainless steel typically shows a linear elastic region followed by a yield point and then strain hardening.
• Stainless steel initially deforms elastically until reaching the yield point

• After the yield point, plastic deformation occurs with strain hardening

• The graph may show a slight decrease in stress before reaching ultimate tensile strength

• Fracture occurs after the ultimate tensile strength is r

Q1. Difference between latch and flip flop
Ans. 
Latch is level triggered, while flip flop is edge triggered. Latch is asynchronous, while flip flop is synchronous.
• Latch is level triggered, meaning it changes output based on the input level. Flip flop is edge triggered, meaning it changes output based on the edge of the clock signal.

• Latch is asynchronous, meaning it can change output at any time. Flip flop is synchronous, meaning it changes output only at specific ti...read more

Q2. What is amplitude modulation
Ans. 
Amplitude modulation is a method used in electronic communication to encode information on a carrier wave by varying the amplitude of the wave.
• Amplitude modulation involves varying the amplitude of a high-frequency carrier wave in proportion to the waveform being transmitted.

• The modulating signal is the signal that contains the information to be transmitted.

• The carrier wave is the high-frequency signal that is modulate...read more
