Walterke, please explane what is wrong that equation. I appreciate the advice, the rock is falling on a solid surface, the significance of the answer I am after is very minor, a best geuss would do to be honest but I did want something a little better than that

Thanks for the replys guys, quick question can I just do this to get a rough answer? v^2 = 2*g*h = 7m/s KE= 1/2*m*v2 = 784j Force at impact = KE/distance = 318N - seems very low, I know alot of you are saying I should be working out energy etc, but does this work for a rough answer? Cheers

Dont worry, I am not a student. this is for a actual problem, the force i am trying to calculate is part of a much bigger equation which will lead to me buying components and actually building something, hence the reason im only after a rough answer because its not massivly significant

Unfortunately I don't know time, the rock is 32kg falling a distance of about 2.5m, if that helps at all? Cheers

Thanks for the replies, I am after only after a rough answer. Jboggs, yes the rock is simply falling, so does that mean I can assume the acceleration is 9.81? Cheers

no I just didnt think it was that relevent, sorry this is it: I am trying to work out the impact force of a rock falling and hitting a surfce, dont need to worry about it bouncing or breaking up etc, just the basic force. I was thinking KE/distance, (which i need velocity for the kinetc energy)...

Hi, I am trying to work out impact velocity, im tryng to use v^2=u+2*as I know what my distance (s) is I know what my inital velocity (u) is But i dont know my acceleration And I dont know my time I was trying to use f=mg (i know what the mass is) then use a=f/m - but obviously end up with...

change the quantity, I have done it before but I cant remember how I did it.

Hi, How do you manualy edit the hole quatity in a hole table on solidworks? Thanks

Fantastic thank you both very much!

pietje, I tried that and set it to .123 but it still wont do 'trailing zeros' when it is a whole number. Adding a note is'nt an option either as this is how the client wants it done unfortunatly.

Hi, Im trying to put dimensions on a drawing, which all have to be to 1 decimal place, which is fine for the dimensions which are X.XX, but some of them are simply 100mm, how do I make that 100.0mm. If I try to change it on the dimension pannel to .1 or even .12345 ect, nothing happens it just...
