Question
The assembly shown below has three teethed circular objects (Pinions) and two teethed flat objects (Racks), which are perfectly mating with each other. Pinions can only rotate clockwise or anti-clockwise staying at its own center. Racks can translate towards the left () or the right () direction.
If the object A (Rack) is translating towards the right () direction, the correct statement among the following is
If the object A (Rack) is translating towards the right () direction, the correct statement among the following is
Correct answer
(B) Object B translates towards the left direction.
Solution
1.Rack A moves Right ().
2.Rack A is in mesh with Pinion P. Moving A right causes Pinion P to rotate Clockwise (CW).
3.Pinion P is in mesh with Pinion Q. P (CW) causes Pinion Q to rotate Anti-Clockwise (ACW).
4.Pinion Q is in mesh with Pinion R. Q (ACW) causes Pinion R to rotate Clockwise (CW).
5.Pinion R is in mesh with Rack B. Pinion R rotating Clockwise (CW) pushes Rack B towards the Left ().
Therefore, Object B translates towards the left direction.Continue learning with Success Tracker
