Deflection of Beams

[@kevinnyabwan4304]

Very helpful, thanks a lot.
Im kindly requesting for assistance on this one please. On mechanics of machines, the topic is hoists and drums.
A mine cage of mass 800kg is to be raised from a depth of 120m to ground level using a hoist drum of mass 120kg and radius of gyration 0.6m. The drum is 1.4m and the speed reduction gear ratio is 12:1 with an efficiency of 85%. A balance mass of 100kg is to be used. The mass and radius of gyration of the motor rotor are 20kg and 0.4m respectively. The mass of the hoisting rope is 1kg/m. Determine the power drawn from the hoisting motor if the velocity and acceleration of the cage at the start of its motion are 5m/s and 0.8m/s^2 respectively

That made my homework a lot easier! Thanks!
But I still don’t really understand what “E” is.

young modulus. its a constant number for steel. it ranges from 190GPa to 210GPa in a room temperature

Thats great

[@jeromedozie7125]

Awesome thanks.

[@rzgarasadd2395]

when we com to site see a slab warped , how do you know is it deflected or bent ?

Good video❤❤

How to come 5/384 please explain sir in detail
Because I am not understanding any value sir

[@civilengineering94]

These are the factors derived. I will upload separate video on that.

[@worldofcivil326]

pls join there for model question paper analysis

[@mtenga8]

derivation sir

[@civilengineering94]

Very soon
