Question 338General Subjects - Assistant Engineer

The correct answer is D) Electromagnetic clutch. Electromagnetic clutches allow a certain degree of slip within limits, which is a key feature that distinguishes them from other types of clutches. This slip is caused by the magnetic field that engages and disengages the clutch, allowing for a controlled and gradual transfer of power between the driving and driven components. The other options are incorrect because: A) Inflatable tire type clutches do not allow for slip, B) Flexible couplings are designed to accommodate misalignment, not slip, and C) Multiple disk friction clutches rely on the friction between the disks to engage and disengage, without allowing for slip.
