Question

The dips of the normal and overturned limbs of a horizontal-overturned antiform are 30⁰ and 70⁰, respectively. The interlimb angle of this fold is _______ degrees. (In integer)

Answer 1

Correct Answer: 40

Calculating the Interlimb Angle of a Fold 

Step 1: Understanding the Formula

The formula to calculate the interlimb angle of a fold is given by:

\[ \text{Interlimb Angle} = \text{Dip of Overturned Limb} - \text{Dip of Normal Limb} \]

Where:

• Dip of Normal Limb is the dip of the limb that is not overturned.
• Dip of Overturned Limb is the dip of the limb that is overturned.

Step 2: Substituting the Given Values

Given that:

• Dip of Normal Limb = 30°
• Dip of Overturned Limb = 70°

Substituting these values into the formula:

\[ \text{Interlimb Angle} = 70^\circ - 30^\circ = 40^\circ \]

Final Answer:

Thus, the interlimb angle of the fold is: 40°.
