Let us find out the material required for making 4 nos. MS window grills as shown below.
The type of material used to make this window grill is shown in the below-given drawing.
Given data:
MS grill length = 790mm.
MS grill width = 660mm.
No. of MS grills to be made = 4nos.
The material used in the MS grill frame 👉 MS flat of 30 × 5mm. size.
The material used in MS grill mesh 👉 MS square bar of 12mm. size.
Holdfast is made of an MS square bar 👉 120mm in length.
The crossbar of holdfast 👉 2nos., each of 50mm. length.
Calculation:
Now, let us calculate the required number of MS materials.
1. MS flat:
The total length of the MS flat for a single window
= [ (2nos. × window grill length ) + (2nos. × window grill width)]
= [ ( 2nos. × 790mm. ) + ( 2nos. × 660mm.)]
= [ 1580mm. + 1320mm.]
= 2900mm.
= 2.90m.
2. MS square bar:
The length of the MS square bar for a window mesh
= [ ( no. of horizontal bars × window grill length ) + ( no. of vertical bars × window grill width )]
= [ ( 6nos. × 790mm. ) + ( 6nos. × 660mm.)]
= [ 4740mm. + 3960 mm. ]
= 8700mm.
= 8.7m.
3. MS holdfast:
The length of the MS square bar for window holdfast
= [ (holdfast length )+ (2nos. × crossbar length) ]
= [ 120mm. + ( 2nos. × 50mm.)]
= 220mm.
= 0.22m.
As you know, the available standard length of MS materials 👉 6m.
Let us calculate the total no. of materials in table format.
