what if i want to lap a 20mm dia and a 16mm dia together wat
will be the lap length??
a) 1m
b) 80mm

Answer Posted / rethina kumar

generally we use this constant for rod lap (58D) D=diameter of rod ( answer in mm )

while we connecting 20mm rod to 20mm rod lap will be (58x20=1160mm)
connecting 16mm to 16mm lap is (58x16=928)

in this question 16mm rod is laid above 20mm rod , so lap length min 80mm max 928mmm

Is This Answer Correct ?    7 Yes 2 No
