I know what it means but what I don't understand is where it comes from I mean like when do I know when to use it?
For example:
150mm dia
Elasticity 200gpaBut I wrote it down as 150x10^-3 and 200x10^9
I could of left it as 150 and 200 but I changed it to ^ instead, why did I do it and how...
Well speaking to my teachers and looking at UCAS website, A levels or any equivalents are fine?
I'm doing my HNC if that even counts and considering the HND.
There is a course just called "Physics" and another called " Theoretical Physics and mathematics".
What is the difference? One course...
Ok, i need help, how do i plot the sheer force diagram?
I did a rough example:
+
+2.28 for 1m then with the 2KN i come down to .28 for 2.5m and with the 3KN i come down to -2.72 for 3.5m and then back up to 0 inbetween the plus and minus.

Is this rough version ok?
hey guys and ladies, i need help on choosing a course.
On the UCAS website, i chose the course 'Physics' and i got multiple choices pop up:
Applied Physics
Atmosphere Physics
Biomedical Physics
Chemical Physics
Computational Physics
Electronic / Electrical
Engineering Physics...
ƩƩHomework Statement
I am having issues finding Ra and Rb using the Sum of the momemnts, it's ƩMCW = MACW.
I need to find the position of the maximum and minimum bending moments.
The Supported beams in question is 3.5m long. Starting from the left and moving towards the right: 1m in...
Ok here is my attempt, possibly all wrong.
I guessed the tracktive effort is 2100.2
I got this by looking at the D'Alembert's equation:
Tracktive effort = gravitational force + inertia resistence + frictional resistance.
For Gravitational force, i put 1350 as that is mass and a...
Homework Statement
Hey, this is the first time i have ever done this and i like to know how to solve it.
A car with a mass of 1350kg is tested by having it accelerated up a road with a slope of 1 in 5,increasing in speed from 2.5 to 12 m/s,covering a distance of 100m, agaisnt a frictional...
