Answer:
The major effects of ice accretion on the aircraft is that it disturbs the flow of air and effects the aircraft's performance.
Explanation:
The ice accretion effects the longitudinal stability of an aircraft as:
1. The accumulation of ice on the tail of an aircraft results in the reduction the longitudinal stability and the elevator's efficacy.
2. When the flap is deflected at with no power there is an increase in the longitudinal velocity.
3. When the angle of attack is higher close to the stall where separation occurs in the early stages of flow, the effect of ice accretion are of importance.
4. When the situation involves no flap at reduced power setting results in the decrease in aircraft's longitudinal stability an increase in change in coefficient of pitching moment with attack angle.
Answer:
a)
b)
c)
Explanation:
From the question we are told that:
Interior temperature
outside temperature is
Rate
a)
Generally electric resistance heating is the heat transfer from interior building
Therefore
b)
COP =3
Generally the equation for coefficient of performance is mathematically given by
Therefore
c)
Generally the equation for coefficient of performance is mathematically given by
Therefore
Answer:
Explanation:
Given
velocity at A is
For
velocity is increasing at
Tangential acceleration is given by
at
thus
Velocity in terms of Displacement is given by
When car has traveled th of distance i.e.
on solving we get
Thus velocity at
(b)Acceleration when car has traveled three-fourth the way of track
normal acceleration
Tangential acceleration
Net acceleration
