Sorry, forgot to mention I tried using that equation using the sine rule and it didnt work out due to the arcsin of the sin. Either way I don't believe this is the correct way of going about forming the equation from the geometry
That is the equation I ended up getting at the bottom labelled 1...
The two equations found from resolving vertically and horizontally, T2 is now known as the weight 18kg, however alpha, beta and T1 are still three unknown
NEW
I can not form a correct third equation, I have tried using the geometry but something always seems to be missing
Ok, thank you.
Even given this assumption, I do not see enough information provided to be able to work out the forces exerted at the point of attachment
I managed to get an expression for alpha in terms of beta and the distances, using the sine rule.
However I still do not see how it would be possible to find the components of the forces exerted at the point of attachment
Is it reasonable to assume the tension T2 in the second string (to the...
Homework Statement
Derive an expression for the angle alpha and determine the initial horizontal and vertical forces exerted at the point of attachment of the bell rope to the plank.
The system is in static equilibrium
Both ropes are light ie negligible mass.
The point of attachment has been...
