Prob . 2
Amsweet
( a. ) The value of & = 30 %%
I = 10 mm
Thus we have , R - 1. 0 x 50 - 1
30
R = 0 - 66 mm
The bend angle has no effect on the answer
because it is not a factor in the strains
involves in bending
- 9712
( b ) The bend allowance is the are length of
the bend as measured along the neutral
anis of the material you are using
re .N
Firstly consider the flate sheet, and bent the
sheet metal with the bend angle of go degrees
leg lengths
R
a
BA
K
lug length 2
we can calculate the leg length , & ? as follows;
leg length 1 - a - R
leg length 2 - b - R...
