In a helocopter, to change from hovering to flying forward, you adjust the cyclic. You push it forward, which increases the pitch of the rotor at the rear, decreasing it at the front, which tilts the aircraft forward, causing it to move forward. You also adjust the collective up, to increase the overall pitch, causing the aircraft to go up, because you want to quickly gain altitude in order to have a safe margin to auto-rotate in case the engine fails.

What is the type of current in the maglev train ac or dc?

maglev train works on alternating current..The electric current supplied to the coils in the guideway walls is constantly alternating to change the polarity of the magnetized coils. This change in polarity causes the magnetic field in front of the train to pull the vehicle forward, while the magnetic field behind the train adds more forward thrust.


What is the behavior of a forward and reverse biased diode?

Forward Resistance:def: It is resistance offered by diode to the forward bias is known as forward resistance.This resistance is not the same for the flow of DC as for the changing current. Accordingly this resistance is of two types :1. DC FORWARD RESISTANCE.2. AC FORWARD RESISTANCE.1. DC forward resistance: It is the opposition by diode to the DC. It is measured by the ratio of DC voltages across the diode to the resulting DC current through it.2. AC forward resistance: It is the opposition offered by the diode to the changing current. It is measured by the ratio of change in voltage across diodes to the resulting change in current through diode. The AC forward resistance is more significant as the diodes are generally used with alternating voltage.Reverse Resistance:def: The resistance offered by the diode to the reverse bias is known as Reverse Resistance. It can be DC reverse resistance or AC reverse resistance depending upon whether the reverse bias is direct or changing voltage. Idealy the reverse resistance of a diode is infinte however in practice the reverse resistance is not infinite because for any value of reverse bias, there does exist a small leakage current. It may be emphasized their that reverse resistance is very large compared to the forward resistance.These Definitions are from PRINCIPLES OF ELECTRONICS by V.K MEHTA and ROHIT MEHTA

What happens when you switch to reverse while going forward?

Switching to reverse while a vehicle is moving forward can cause significant damage to the transmission and drivetrain. The sudden change in direction puts immense stress on the gears, potentially leading to mechanical failure. Additionally, it can create a loss of control, increasing the risk of accidents. It's crucial to come to a complete stop before shifting into reverse to avoid these issues.

How do spacecrafts fly?

Spacecrafts fly by generating thrust from their rocket engines, which propels them forward. Once in space, they continue on their trajectory in a state of free fall, using the principles of inertia and gravitational forces to navigate. Their course can be adjusted by firing thrusters or engines to change direction or speed.
