1In the ISO 286 hole-basis system of fits used in construction mécanique, which statement is correct?

A.The hole has a fundamental deviation of zero (H), and the shaft tolerance class is chosen to produce the required clearance or interference

B.The shaft is always made to H7 and the hole class is varied

C.Both hole and shaft must use the same letter so that the fit is guaranteed

D.The hole-basis system can only produce clearance fits

Explanation: In the hole-basis system the basic hole is an H class (lower deviation EI = 0), so the smallest hole equals the nominal size. Clearance, transition or interference is then obtained by pairing that hole with different shaft classes such as g, k or p. This is the usual workshop convention because standard reamers and gauges produce H holes economically.

2On a definition drawing the fit is written Ø25 H7/g6. What do the capital H and the lowercase g identify?

A.H is the shaft class and g is the hole class

B.H and g are both IT grades

C.H is the hole tolerance class and g is the shaft tolerance class

D.H means interference and g means clearance

Explanation: ISO 286 writes the hole class with a capital letter and the shaft class with a lowercase letter. H is therefore the hole (here IT7 with EI = 0) and g is the shaft (here IT6, slightly under the nominal size). The numbers 7 and 6 are the IT grades that set the width of each tolerance zone.

3The ISO 286 pairing H7/g6 is classified as which type of fit?

A.Interference (press or shrink) fit

B.Clearance (sliding) fit

C.Transition fit

D.Force fit that always requires heating the hole

Explanation: H7/g6 is a close running or sliding clearance fit: the g6 shaft always finishes slightly under the H7 hole, so a guaranteed minimum clearance remains. It is used for precise location with free movement, such as sliding pins, guide bushes and precision spigots.

4For a given nominal diameter, how does a change from IT7 to IT6 affect the tolerance?

A.The tolerance zone becomes wider, so manufacture is easier

B.The fundamental deviation letter changes from H to h

C.The fit type automatically becomes an interference fit

D.The tolerance zone becomes narrower (higher precision, higher cost)

Explanation: The IT (International Tolerance) grade number is the width of the tolerance zone. A smaller grade number is a tighter band: IT6 is narrower than IT7 for the same size. Finer grades need more accurate processes (grinding, honing, reaming) and cost more, which is why drawings reserve IT6–IT7 for functional fits and use IT12–IT14 for raw or non-mating sizes.

5A hole is specified Ø25 H7. In the 18–30 mm size band, IT7 = 21 µm and H has EI = 0. What are the limit sizes of the hole?

A.25.000 mm to 25.021 mm

B.24.979 mm to 25.000 mm

C.24.989 mm to 25.011 mm

D.25.000 mm to 25.013 mm

Explanation: For an H hole the lower deviation EI is zero, so the smallest hole equals the nominal 25.000 mm. The upper deviation ES equals +IT7 = +21 µm, so the largest hole is 25.021 mm. This 0 / +21 µm band is the standard H7 hole used throughout F1 fit calculations in that size range.

6On a centre lathe (tournage), which statement correctly describes the relative motion?

A.The cutting tool rotates and the workpiece is fed past it, as in milling

B.The workpiece rotates about the spindle axis and the tool is fed along or across that axis

C.Both tool and workpiece remain stationary while a broach is pulled through

D.The workpiece is struck by a reciprocating ram, as on a shaper

Explanation: Turning generates surfaces of revolution: the part is clamped in a chuck or between centres and rotates, while a single-point tool feeds longitudinally (cylindrical turning) or radially (facing). That kinematic pair is the defining difference between tournage and fraisage.

7Compared with turning, what is the characteristic kinematics of milling (fraisage)?

A.The workpiece always rotates faster than the cutter

B.A single-point tool is held stationary while the part spins

C.A multi-tooth cutter rotates and the workpiece is fed relative to the cutter

D.Material is removed only by plastic displacement, never by chips

Explanation: In milling a rotating multi-tooth cutter (end mill, face mill, slab mill) provides the cutting speed, while the table feed moves the workpiece. Each tooth takes a chip; climb and conventional milling differ only in the direction of that feed relative to cutter rotation.

8For general-purpose drilling of carbon steel with a standard HSS twist drill, the included point angle is typically:

A.118°

B.60°

C.90°

D.180°

Explanation: A standard jobber twist drill for steels and general materials is ground to an included point angle of about 118°. Harder alloys and stainless steels are often drilled with a flatter 135° split point, while wood bits are much sharper. The two cutting lips must be of equal length or the hole will run oversize.

9For Ø25 H7/g6 in the 18–30 mm band, the hole is 25.000 / 25.021 mm and the g6 shaft is 24.980 / 24.993 mm. The minimum clearance is:

A.0.041 mm

B.0.021 mm

C.0 mm (line-to-line)

D.0.007 mm

Explanation: Minimum clearance is smallest hole minus largest shaft: 25.000 − 24.993 = 0.007 mm (7 µm). Because that value is positive, H7/g6 is a guaranteed clearance fit. Maximum clearance would be 25.021 − 24.980 = 0.041 mm.

10After a hole has been drilled undersize, which finishing operation is used to bring it to a precise diameter and improve roundness and surface finish?

A.Knurling

B.Reaming (alésage à l'alésoir)

C.Parting-off

D.Spot-facing only

Explanation: Reaming is a finishing cut that removes a small remaining stock (typically a few tenths of a millimetre, depending on diameter) with a multi-flute reamer. It corrects drill wander slightly, calibrates the diameter for an H7-class hole, and improves Ra. The hole must already be drilled, bored or core-drilled on location.

Bac F1 Burkina Faso: Suggested Study Strategy

1Learn ISO fit and tolerance notation used on mechanical drawings.

2Re-derive beam and statics results rather than memorising only.

3Practise reading industrial drawings (views, sections, surface finish).

4Work the shared F-series mathematics paper after concept review.

Frequently Asked Questions

Is F1 the same as F2?

No. F1 is construction mécanique. F2 is a distinct industrial-tech series. This bank covers F1 only.

Does the official F1 exam include practical work?

Yes. Technical bac series combine written papers with practical/drawing work. These MCQs cannot certify workshop skill.
