Newton's second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics.
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:
F = 75[J]
Explanation:
We know that work is defined as the product of force by distance.
In this way we have two forces, the weight of the block down, and the force that bring about the block to rise.
where:
W = work = 50 [J]
d = distance = 2 [m]
Fweight = 50 [N]
Fupward [N]
Now replacing:
Answer:
F= 9492.12 N
Explanation:
Given that
mass, m = 1598 kg
Initial velocity ,u= 0 km/h
Final velocity v= 93.9 km/h
v =26.08 m/s
Distance ,d= 57.2 m
We know that
v² = u² + 2 a d
a=acceleration
u=initial velocity
v= final velocity
d=distance
26.08²= 0² + 2 x a x 57.2
a= 5.94 m/s²
We know that
Force = mass x acceleration
F= m a
F= 5.94 x 1598 N
F= 9492.12 N
