A tensile test is performed on a 9 mm thick sample of PVC of width 40 mm.The sample was tested to fracture at room temperature and which point the sample had a total length of 66mm and the force measured was 22 kN. Given that the original length was 65 mm, calculate the following to 2 decimal places: a) The stress at the point of failure 8.46 b) The fracture strain = 0.02 Submit part 2 marks Unanswered b) Given that the shunt is made from a cylinder of manganin of 48.2 x 10-8 m and is 50cm long, what should its diameter (D) be? Take to be 3.142 and give your answer to 2 decimal places. D = cm Submit part 1 mark The diagram below shows a meter shunted by a parallel resistance Rs. The maximum value for Im is 9 mA and the meter has a resistance (Rm) of 0.6 2. Given that the maximum current (I) is 25A: Meter R M M S RS Shunt a) What should the shunt resistance (Rs) be? Give your answer to the nearest whole R = +- D S Given that the wire comprises of 150 turns and the flux density generated by the magnets is 600mT :- What current is required to be passed through the coil if it is required to generate 1Nm? | = mA Give your answer to 2 decimal places in mA and take into account that both halves of the coil will interact with the magnet. Submit answer 1 mark Consider the motor below with a coil radius of 15cm and effective length of 21cm. + D N B X S S Given that the wire comprises of 150 turns and the flux density generated by the magnets is 600mT :- Given that the wire comprises of 110 turns :- What is the flux density (B measured in milliTesla) is required to be present if the coil is required to generate 6V at 1600rpm? B= mT Give your answer to the nearest whole number. Use 3.142 for and consider that both sides of the coil are within the magnet's field. Submit answer 1 mark Consider the generator below with a coil radius of 20mm and effective length of 2cm. N Given that the wire comprises of 110 turns :- B S S X
