Calculate FjDW150 D240mm Im not sure what W is supposed to b

Calculate F_j=DW/150. D=240mm. I\'m not sure what W is supposed to be? I have a 15kg weighing tank mass and a 600g beam weight.

Solution

>> Here, W represents total weight of the system.

So, W = Weight of Tank + Beam Weight

=> W = 15 + (600/1000) = 15.6 Kg ...

Now, F_j = W *D /150

and, D = 240 mm = 0.24 m

>> Putting all values,

=> F_j = 15.6*9.81*0.24/150 = 0.2449 N .... ANSWER....
