engineering recuitment HPCL Engineer Mock Test 2024 Production Engineering (Manufacturing) Metrology and Inspection Limits, Fits and Tolerances
A hole and a shaft have a basic size of 25 mm, and are to have a clearance fit with a maximum clearance of 0.02 mm and a minimum clearance of 0.01 mm. The hole tolerance is to be 1.5 times the shaft tolerance. The limits of both hole and shaft using hole basis system will be
1
low limit of hole = 25 mm, high limit of hole = 25.006 mm, upper limit of shaft = 24.99 mm and low limit of shaft = 24.986 mm
2
low limit of hole = 25 mm, high limit of hole = 25.025 mm, upper limit of shaft = 24.8 mm and low limit of shaft = 24.75 mm
3
low limit of hole = 24 mm, high limit of hole = 25.006 mm, upper limit of shaft = 25 mm and low limit of shaft = 24.99 mm
4
low limit of hole = 25.006 mm, high limit of hole 25 mm, upper limit of shaft = 24.99 mm and low limit of shaft = 25 mm
