A cast iron beam 20mm x 20mm in section and 1m long and simply supported at the ends fails when a central load of 640N is applied. What UDL(Uniformly Distributed Load) will break a cantilever of the same material 50mm wide, 100mm deep and 2m long? 

Answer is 5 kN/m. 

Plz tell the solution. You can also write the solution on a page .. and take the pic and send me the link of the pic of solution. 

Do whatever you want .. but please give the solution ASAP. 

I have attached a picture of question ... if you can solve question 6 also, then please give its solution also.
