25Nm-2
50Nm-2
500Nm-2
1000Nm-2
Correct answer is D
\(P_2 = \frac{p_1 \times T_2}{T_1} = \frac{500 - 520}{65}\)
= 1000Nm-2
49.2oC
60.6oC
80.0oC
84.7oC
Correct answer is A
85\(\Omega\) ........100oC
52\(\Omega\) ........\(\theta\)oC
20\(\Omega\) ........0oC
\(\frac{52 - 20}{85 - 20} = \frac{\theta - 0}{100 - 0}\)
\(\theta = \frac{32 \times 100}{65} = 49.2^oC\)
32.0N
26.7N
16.0N
13.3N
Correct answer is D
E x 3 = 80 x 0.5
E3 = 40
E = \(\frac{40}{3} = 13.3N\)
21
38
48
151
Correct answer is D
P = \(\frac{25}{50} = 0.5\)
V.R = \(\frac{2\pi D}{p} = \frac{2 \times 3.142 \times 12}{0.5}\)
= 151
10.0
13.3
17.5
25.0
Correct answer is B
M.A = \(\frac{load}{effort} \frac{5000N}{500N} = 10\)
V.R = \(\frac{M.A \times 100}{V} = \frac{10 \times 100}{75} = 13.3\)
