Question 1

In mechanical systems modeling, how many degrees of freedom (degrés de liberté) does an ideal pivot joint (liaison pivot) allow between two rigid bodies?

1 rotational degree of freedom and 0 translational degrees of freedom 1 translational degree of freedom and 0 rotational degrees of freedom 1 rotational and 1 translational degree of freedom 2 rotational degrees of freedom and 0 translational degrees of freedom

Correct Answer:

1 rotational degree of freedom and 0 translational degrees of freedom

Question 2

What degrees of freedom are eliminated by an ideal planar joint (liaison appui plan) whose normal vector is aligned with the z-axis?

Translation Tz and rotations Rx and Ry (3 degrees of freedom eliminated) Translations Tx and Ty and rotation Rz (3 degrees of freedom eliminated) Translations Tx, Ty, and Tz (3 degrees of freedom eliminated) Rotations Rx, Ry, and Rz (3 degrees of freedom eliminated)

Correct Answer:

Translation Tz and rotations Rx and Ry (3 degrees of freedom eliminated)

Question 3

Which set of degrees of freedom is permitted by a spherical ball joint (liaison rotule ou sphérique) centered at the origin?

3 rotations (Rx, Ry, Rz) and 0 translations 3 translations (Tx, Ty, Tz) and 0 rotations 1 translation (Tz) and 2 rotations (Rx, Ry) 2 translations (Tx, Ty) and 1 rotation (Rz)

Correct Answer:

3 rotations (Rx, Ry, Rz) and 0 translations

Question 4

In the ISO system of limits and fits, what type of fit is represented by Ø30 H7/g6?

A clearance fit (ajustement avec jeu) An interference fit (ajustement avec serrage) A transition fit (ajustement incertain) A shrink-fit (emmanchement à la presse)

Correct Answer:

A clearance fit (ajustement avec jeu)

Question 5

For an assembly specified as Ø40 H7/p6, the hole tolerance is Ø40 (+0.025 / 0) mm and the shaft tolerance is Ø40 (+0.042 / +0.026) mm. What are the maximum interference (Serrage maxi) and minimum interference (Serrage mini)?

Serrage maxi = 0.042 mm, Serrage mini = 0.001 mm Serrage maxi = 0.042 mm, Serrage mini = 0.026 mm Serrage maxi = 0.067 mm, Serrage mini = 0.001 mm Serrage maxi = 0.025 mm, Serrage mini = 0.016 mm

Correct Answer:

Serrage maxi = 0.042 mm, Serrage mini = 0.001 mm
