A force of 500N1 is applied to a steel wire of cross-sectional area 0.2m2, The tensile stress is
2.5x104Nm-2
1.0x102Nm-2
1.0x103Nm-2
2.5x103Nm-2
Correct answer is D
\(Stress = \frac{Force}{Area}\)
\(Stress = \frac{500}{0.2} = 2500\)
= 2.5 x 103Nm-3

The diagram above shows a circle PQRS in which ∠PRQ = 54o and ∠SPQ = 97o. Find ∠PQS
61o
51o
43o
39o
29o
Correct answer is E
PSQ = 54o ∴PQS = 180o - (97 + 54)o = 29o
