Hello all,
I have recently been attempting to refresh my memory in regards to method of joints and have been making some reasonable progress, however I have ran into a stumbling block that has left me quite puzzled.
I have been using the Skyciv truss calculator to verify my work and for the...
Hello friends,
I have a situation where I am looking to pull a load and would like to better understand the forces involved.
In the first scenario I am pulling a load in a straight line, the load cell reads 10kN.
In the second scenario I would like to pull the same load at an angle of 150o...
Hello friends,
I am having a hard time understanding thermal conduction and was hoping someone could shed some light for me.
I am looking to protect a component from heat by placing a thermal barrier between it and the heat source, the heat applied to the surface of this barrier would be...
I'm wondering if there is a calculation that can be used to work out the maximum stress on an object upon impact.
Say for example an object strikes a rigid wall, how would one go about calculating the stress on that object?
My apologies. Here is a rather crude sketch of the problem.
The load acting on the hole is supplied by a pin of diameter 0.0195m.
This is all the information that is given to me, so assumptions may have to be made I would imagine...
Hello friends, I have a small query regarding a force being applied to a surface...
I have a force of 0.1MN which is being applied in the -y direction onto a surface.
Now I know that if said surface was flat, I would divide the force by the area to give me the stress.
However the force is...
Thank you for your swift response!
This indeed confirms my confusion, I have a killawatt meter plugged in between my inverter and appliance. the meter gives a reading of 0.1A. Neglecting the efficiency of the inverter shouldn't my reading be 2A? (24W/12V)
Hi friends,
I am having a little difficulty understanding how amp hours being pulled from a battery are calculated, any help would be much appreciated!
I have a 12v 125Ah deep cycle battery. Research has told me that for DC appliances you divide their wattage by 12V to give the amps, so...
Thank you for your replies fellas!
I will elaborate on what it is I am doing, hopefully this will clear some things up.
I recently purchased an inverter which I have connected to a battery. As the inverter has a metal casing the manufacture states that it should be earthed, obviously to...
Hi friends, simple question here.
I have a system that needs to be earthed, currently I am connecting it to an earthing rod which I have outside, however it would be more convenient for me to have the system indoors.
Would wiring the Earth connection to the Earth pin in a standard UK plug...
Hi friends!
I have recently started a small project where I had hoped to build a simple sun tracker.
My initial plan involved 2 Photovoltaic cells mounted at either end of a panel which was attached to a shaft which was then attached to a small DC motor. Both cells were hooked to the motor...
So I'm not the most knowledgeable person when it comes to electrical connections and the like but I tend to have a fair idea. I'm currently planning on building a solar panel with the hope that it will power appliances throughout my house.
My planned set up is as follows:
>> 36 0.5V 3.6A...
Hi friends :)
I was wondering... I have a 12V deep cycle battery which I have connected to a 300W 12V DC-240V AC. Now if I were to plug multiple different appliances into it at the same time would I be right in saying that, for example, if I had an appliance that consumed 100W and another...
