Hmmmm not sure! I may be on completely the wrong track here but these are my thoughts... if the object was accelerating at 10m/s2 then it would have no force against it so tension in the cable would be zero. However, if the object was stationary it would be working against the full gravitational...
I do apologise for being such a numpty it's been far too many years since I last attempted anything like this so you'll have to bear with me.
Right, I presume what you're saying is mass x gravity - T = mass x acceleration
In that case, 5000x10 - T = 5000x8.6
T...
Thank you for the advice what a complete idiot to miss out something so basic :-)
So I need to use Force=mass x acceleration to determine the actual 'downward pull', for want of a better word, of the load.
In that case if I have (5*10^4) * 1.4 the force would be 7 *10 ^4.
Would the rest of my...
Homework Statement
A winding engine lowers a load of 5 tonne at the rate of 1.4m/s2 for a distance of 10m. Assuming that the load is suspended from a steel rope 12mm in diameter calculate the stress and the extension in the rope after traveling this distance. Assume Esteel=200 GN/m2 and...
