Question

In the block diagram, the net slip (=100 m) is resolved into strike slip (s) and dip slip (d) components. The value (in m, correct to two decimal places) of "s" is ..... 

Hint:

When resolving a slip into strike and dip components, use the sine function for strike slip and the cosine function for dip slip.

Answer 1

Correct Answer: 86

Step 1: Understand the trigonometric approach to resolving slip components.
In structural geology, the net slip can be resolved into strike slip and dip slip components using trigonometric functions. The diagram provides the angle between the fault plane and the horizontal. The net slip is 100 m, and the dip angle is 30°. We use the formula for resolving slip components: \[ s = \text{net slip} \times \sin(\theta) \] Where: - \(\text{net slip} = 100 \, \text{m}\) - \(\theta = 30^\circ\) (the dip angle)

Step 2: Calculate the strike slip (s).
Substitute the values into the formula: \[ s = 100 \times \sin(30^\circ) = 100 \times 0.5 = 50 \, \text{m} \] Thus, the value of strike slip (s) is 50.00 m.
