Question 12
A
343.32N
B
233.33N
C
333.33N
D
334.33N
Explanation
\(\frac{MA}{VR}\times\frac{100}{1}=efficiency\)

\(\frac{L}{E}\frac{1}{VR}\times\frac{100}{1}=75\)

\(\frac{1000}{E}\frac{1}{4}\times\frac{100}{1}=75\)

\(E = \frac{250 \times 100}{75}\)

E = 333.3N

Question 13
A
90%
B
80%
C
85%
D
87%
Explanation
VR = 800/200 = 4
\(Efficiency = \frac{MA}{VR} \times \frac{100}{1}\)

\(Efficiency = \frac{L}{E} \times \frac{1}{VR} \times \frac{100}{1}\)

\(Efficiency = \frac{800}{250} \times \frac{1}{4} \times \frac{100}{1}\)

= 78.74%
= 80%

Question 14
A
2.5x104Nm-2
B
1.0x102Nm-2
C
1.0x103Nm-2
D
2.5x103Nm-2
Explanation
\(Stress = \frac{Force}{Area}\)

\(Stress = \frac{500}{0.2} = 2500\)

= 2.5 x 103Nm-3
