Great teaching here. The way the tutor went through all the different angles and how things change as a result was very clearly and interestingly presented. I learned a lot from it.
Hi, can you explain how /why the tension in the chain is able to increase to a magnitude beyond the magnitude of the load itself? If the included angle was 179 degrees for example and the tension in the leg is astronomically high, what is it that is producing this 'extra' tension? thanks in advance
Hi Vishnu...you would use the Sin value if you are using the sling-to-HORIZONTAL angle - as is done in US and some other places. In UK and Europe, we work with the sling-to-VERTICAL angle - hence using Cosine. For example, 60 degrees to vertical would be 30 degrees to horizontal. The each of these calculations would arrive at the same result - it's just a different way of doing it.

Thanks very much Helen - glad you like it. What else are you keen to learn?
Excellent explainer video Kevin 👍
Thanks very much for watching :)
I never thought I'd use Pythagoras Theory after leaving school.

Isn't it supposed to be divided by Sin value instead of Cos value to find the Sling tension?
