derive an expression for the depression at the free end of a cantelever
Answers
Answer:
Cantilever beams are simply beams supported at one end with the other end free. In this configuration the one end takes all of the load thus a good anchor is needed to resist the bending moment. (Unless the beam continues on to something else.). This configuration is typically called Encastre.
At times you do not have the ability to avoid using a cantilever beam because of access requirement. Sometime it is used for aesthetic purposes in structures.
By carful design you can make a beam with little deflection but it will have varying values of second moment of ar along its length.
Examples of a cantilever is a spring board. Clearly they are using the fact the board deflects a lot to provide lift to the diver. Other example are many, you just need to look around. Quiet often a bus shelter has a catekever roof, or car parks, or railway stations. They are practical answers to practical problems.
I hope this helps.
