- Homework Statement:
Hi I am stuck on part ii of this question i keep ending up with equations with three unknown variables and don't know how to solve it, any help would be massively appreciated!
- Relevant Equations:
50n×1.2 +1.3×Rd =1000g×0.3
Im not too sure, I don't really see what effect it would have on it, from the answer I am guessing it doubles the force but don't know how they got to that conclusionWell there's not really much difference anyway
So you have correctly calculated that the four sailors exert a force of 1,200N at a distance 1.5m from the centre of the capstan (this is a torque of 1,800Nm). You have been provided with the diameter of the capstan drum, what difference do you think that makes to the tension in the cable?
Please, see:Im not too sure, I don't really see what effect it would have on it, from the answer I am guessing it doubles the force but don't know how they got to that conclusion
Don't use F for a moment, that will confuse everyone!I would assume from the numbers 0.5 T=F as R=0.5 which equals the distance from the cable to the centre but I would have thought that T=0.5 F not the other way round
No problem - and this is all there really is to solving problems using moments/couples/torques, so you can't say you don't understand it any more!Ohh ok i see I didnt realize the forces were balancing out but looking back through the question I can see now
that the moments have to be equal thank you so much you've been a massive help!
