Design a signal conditioning circuit using an NTC thermistor that could measure temperature
within 00C to 300C with ±20C tolerance. The output of this signal conditioning circuit should
be interfaced to an Arduino Uno. The NTC thermistor used for this application is a Standard
Lug NTC manufactured by Vishay. The Ordering number is NTCALUG01A103F [3] [12%]
A 2.5m long steel towing bar of solid circular section diameter 50mm is expected to carry a maximum load of 300kN. The factore of safety is 4; and for the steel the UTS is 540Mnm*-2 (to the power of -2) and the modulas of elasticity is 200 GNm*-2.

Calculate the actual towing capacity of the bar and state whether the proposed limit is acceptable.
I usually Mount the sample (Working Electrode) for potentiodynamics polarization studies to obtain Tafel plots. What is the significance of height of sample which is used for three electrode cell?
Because I recently used sample with height of 3cm and I could not obtain the Tafel plot, the software just gave random scattered points.
I again prepared the same sample by cutting it and decreasing its height to almost 1cm and the results obtained were fine.
So, please tell the significance of height of the working electrode and why does it only gave the scattered data??
Water at a temperature of 15°C produces ice cubes at a temperature of −5°C. Water is taken in at the
rate of 1 kg every 7 minutes and the input power to the machine is 300 W. The specific heat capacity of
water is 4187 Jkg−1K
−1, the specific heat capacity of ice is 2100 Jkg−1K
−1 and the specific latent heat of
fusion is 335 Jkg−1
.
i) Calculate the heat energy extracted per kg of ice produced
This part of the task provides the remaining evidence for the grading criterion P8.
ii) Calculate the thermal efficiency of the ice making machine.
This part of the task provides the evidence for the grading criterion M3.
