All 7 questions on Stress and strain, as a list
- June 2024, Paper 1, Q21 (1 mark): When a force of 0.80 N is applied to a spring, the length of the spring is 90 mm. When a force of 1.30 N is applied to the same spring, its length is 115 mm. Th
- June 2024, Paper 1, Q22 (1 mark): An experiment is carried out using a metal wire to investigate how it responds to a varying tensile force. The cross-sectional area of the wire is constant. Whi
- June 2024, Paper 2, Q4(a) (1 mark): Define strain. [1]
- June 2024, Paper 2, Q4(b)(i) (3 marks): Calculate the Young modulus of the wire. Young modulus = Pa [3]
- June 2024, Paper 2, Q4(b)(ii) (2 marks): On Fig. 4.1, draw a line to show how the stress varies with the strain for the wire up to its limit of proportionality. 5 stress / 107 Pa 4 3 2 1 0 0 1 2 3 4 5
- June 2024, Paper 2, Q4(c) (2 marks): A second copper wire has the same length as the wire in (b) but a larger diameter. Both wires are subjected to a tensile force of 18 N. By placing a tick (3) in
- Specimen, Paper 1, Q20 (1 mark): A wire of diameter d and length l hangs vertically from a fixed point. The wire is extended by hanging a mass M on its end. The Young modulus of the wire is E.
