Question Statement:
An L-shaped cantilever bracket has its vertical limb along the positive y-direction and its horizontal foot extending to the right (+x direction). When reflected across a vertical mirror placed to its right, what is the orientation of the mirror image?
Options:
(A) Vertical limb points upwards (+y) and the horizontal foot extends to the left (-x).
(B) Vertical limb points downwards (-y) and horizontal foot extends to the right (+x).
(C) Vertical limb points downwards (-y) and horizontal foot extends to the left (-x).
(D) The bracket appears rotated in-plane by 180 degrees.
Answer Key:
A
Step-by-Step Solution & Explanation
A vertical mirror reverses the lateral direction (x-axis) while leaving the vertical dimension (y-axis) unaffected: the right-pointing foot now points left.
