When the engine is near the governed RPMand the transmission is in the lower gears, the braking effect of the engine is at its greatest .
It is specified that the legal requirements for the braking system that:
A reasonable distance should be practiced in stopping your vehicle.
Adjournment from the jar or shudder should be smooth and free.
A good braking system’s other necessities are:
Unaffected by heat, water, road grit, dust etc.
Constant continued application while moving downwards from a hill should not decrease its effectiveness and it must have good anti fade characteristics
Adequate durability with economical maintenance and adjustment Its durability must be enough and must have proper adjustment and maintenance.
Answer:
its direction is changing
Move with constant speed or accelerate and will determine direction
Explanation:
Given:
m1 = 0.55 kg
m2 = 0.45 kg
vi1 = +5.8 m/a
vi2 = -3.9 m/a
Solve for V
m1vi1 + m2vi2 = (m1 + m2)V
(0.55 kg)(+5.8 m/s) + (0.45 kg)(-3.9 m/s) = (0.55 + 0.45)V
V = +1.46 m/a
This means that the combined mass after the collision is moving to the right at 1.46 m/s
Initial state the pressure and volume are
P = 1 bar
V = 1 litre
Now the process equation is given as
PV = constant
So now the pressure is increased to
P = 4 bar
so volume must decrease by 4 times
so final volume is
V = 0.25 litre
Now the pressure is constant and volume again increased to V = 1 litre
Now in final step the volume will become constant and again pressure will become P = 1 bar
so this is a cyclic process and figure is attached at following
