What is the angle at which no supports are required according to the left section of the diagram?
Less than 45 degrees
Equal to 45 degrees
More than 45 degrees
Exactly 30 degrees
Answer explanation
The angle at which no supports are required is less than 45 degrees. This is because angles below this threshold can maintain stability without additional support, making 'less than 45 degrees' the correct choice.

At what angle do supports become necessary according to the diagram?
Less than 45 degrees
Equal to 45 degrees
More than 45 degrees
Exactly 30 degrees

Which angle in the diagram is shown as not requiring supports in the middle section?
Less than 45 degrees
Equal to 45 degrees
More than 45 degrees
Exactly 30 degrees
Answer explanation
The angle equal to 45 degrees is the critical point where supports are not needed in the middle section. Angles less than or more than 45 degrees typically require additional support to maintain stability.
