Question

Determine the following statement whether is True or False

1. Adhesive joints are much stronger in tensile loading than shear loading

2.The dominated loading condition in a helical spring is torsion along coils.

3. The principal advantage of conical springs is that the its spring rate is nonlinear

4.The dimensions of a bearing is coded by two-digit series numbers according to ABMA, one digit for width and the other one for diameter.

5. Three key things to determine selection of bearing are load, life and reliability.

6.Straight roller bearings can carry large radial loads and small amount of axial load

7. In the AGMA method of gear analysis, gear strength values are the true material strengths.

Answer 1

1) False

Adhesive joints are strong in shear loading than tensile loading

2)True

Dominated loading in helical spring is torsion in coils

3)True

A conical spring is a nonlinear spring. This means that the amount of force distributed throughout the spring varies. For instance, more force is applied to compress the smaller diameter end of the spring than on the larger end. As a result, there is a more efficient distribution of force.

4)True

5)True

6)True

Straight roller or cylindrical bearings run in cylindrical raceways and have low-friction, high-radial load capacity, and high speed capability

7)True
