Question

Which of the following form(s) can be placed on a flat floor in such a way that there are no overhanging elements, i.e., cantilevers?

• A. A
• B. B
• C. C
• D. D

Hint:

To avoid cantilevers, ensure that the form does not have any part extending beyond its support when placed flat.

Answer 1

The Correct Option is B, C

Step 1: Analyzing the given forms.
Cantilevers are elements that extend beyond a support without being supported at the far end. To avoid cantilevers, the object must rest fully on the flat floor without any overhanging parts.
Step 2: Visualizing the placement of forms.
- (A) has an overhanging element that would not allow it to rest on the floor without cantilevering. - (B) can be placed flatly on the floor without any overhanging parts, making it stable. - (C) similarly can be placed flatly on the floor without cantilevers. - (D) has a significant overhanging part and cannot be placed without cantilevers.
\[ \boxed{(B) \text{ and } (C) are correct.} \]
