Answer:
Velocity of ball B after impact is and ball A is
Explanation:
= Initial velocity of ball A
= Initial velocity of ball B = 0
= Final velocity of ball A
= Final velocity of ball B
= Coefficient of restitution = 0.8
From the conservation of momentum along the normal we have
Coefficient of restitution is given by
Adding the above two equations we get
From the conservation of momentum along the plane of contact we have
Velocity of ball B after impact is and ball A is .
Answer:
If the tapered roller bearing clearance is too tight, the components will bind and overheat due to increased pressure and because the rollers squeeze out too much grease, making the lubricating film too thin.
Explanation:
Answer:
The absolute air pressure, on top of reservoir is 3858.84 kPa
Explanation:
Given
Since
Also,
, hence
KL = 0.5 + 2 +0.2 = 2.7
Pressure loss of pipe =
f from Moody chart at μ = 1.307 × 10⁻³ kg/m·s and
Roughness ε = 0.00026 m whereby, relative roughness is ε/d = (0.00026 m)/ 0.02 m = 0.013
f= 0.042 and
Q = v·A = 1.5 L/s = 0.0015 m³/s
v = Q/A where A = π·(0.02²)/4 = 3.1416×10⁻⁴ m²
v = (0.0015 m³/s)÷(3.1416×10⁻⁴ m²) =4.775 m/s
Pressure loss of pipe, = 3733071.965 Pa
= 3858839.04 Pa
The absolute air pressure, on top of reservoir = 3858.84 kPa
Answer:
diesel fuel is pumped at high pressure to the injectors which are responsible for entering the fuel into the combustion chamber,
when the piston is at the top the pressure is so high that it explodes the fuel (diesel) that results in a generation of mechanical power
