Hi, Im about to start work for an electrical component and wire harnessing manufacturing company. I am joining the company on a graduate scheme and was looking for some advice on what to expect from the job. Also if there's any background reading or knowledge i could obtain before i start...

Thank you for your help i understand now. Basically the only piece of information that confused me was that G was equal for both the bar and the bit. I can calculate the final torques now and just in time for my exam. Thanks Ben

Were not given the torque in the question. So would i need to calculate the torque in the cylindrical bar using the angle of twist, J, the length L and G? (angle of twist) =(TL)/(JG) or, and, (G (angle of twist))/L = T/J They both give me the same result. (I don't understand why...

Well the torque is transmitted through the bar i suppose. I guess you take the end of the bit to be fixed. That the screwdriver is being used in a traditional sense. I don't see how you calculate the torque in the bit

Basically what I am finding difficult is working out how to include both the bar and the bit. Do i do the entire calculation taking it as one singular piece or do i calculate the torque required to revolve the bar by 1 degree and then do the same separately for the bit. Would i then just take...

Hi i need some help on solving a question from a past paper. I am revising for an exam in applied engineering mechanics. Question: A screwdriver is designed so that the bit is 5mm wide and 1mm deep and is 25mm long, this is welded to a cylindrical bar 12mm in diameter and 100mm long. If the...

Thanks for your reply, my lecture recommended that i simply insert a generic household or office humidifier into a cardboard box and introduce a step response in the duty cycle (It runs off a PWM signal). Then he recombined i develop a controller with the ability to alter the humidity given a...

I have created a mock up of a humidity chamber which i will soon be integrating into a temperature chamber for undergraduate project. I am confused on how i can control the system. I have currently a humidifier with a relay built in, this relay is going to switch on and off from a PWM signal...
