I believe a connecting rod has a cap, bushing and I-beam whereas a lobe would be found on a camshaft
Answer:
2.35 + j8.34 Ω
Explanation:
Voltage = V
= 240 V rms
supplying power = S
= 8 kVA
power factor = pf
= 0.6
Let P₁ represents one load draws 3kW at unity powder factor
The power angle is:
θ
= cos⁻¹ pf
= cos⁻¹ 0.6 = 53.13°
Complex power supplied source is:
S
= S
< θ
= 8<53.13° kVA
Complex power for first load:
S₁ = P₁ = 3kVA
Since the power angle of first load is θ₁ = 0°
According to principle of conservation of AC power, the power of second load is:
S₂ = S
- S₁
= 8<53.13° - 3
= 6.65<74.29° kVA
Since the second load is a Y connected load the phase voltage:
V
= V
/
= 240/1.732051
= 138.564
= 138.56 V
Complex power of second load:
S₂ = 3 V
² / Z
impedance per phase of the second load:
Z
= 3 V
² / S₂
= 3 (138.56)² / 6.65<74.29°
= 3(19198.8736) / 6.65<74.29°
= 57596.6208 / 6.65<74.29°
Z
= 2.35 + j8.34Ω
Answer: Fire
Explanation: I found a source that talks about the stanges of the 'stone age' and the things that were discovered in certain times. I can attach the link if you would like.
