Muscovite belongs to the mica group of minerals, which are known for their perfect basal cleavage, allowing them to split into thin sheets. These minerals are silicates, typically found in metamorphic and igneous rocks
A hillslope is shown below. If the area over the failure plane is 50 m\(^2\) and the weight of the hillslope material (W) is 2000 tons, the Factor of Safety (FOS) for this hillslope in dry conditions is
Cohesion along failure plane = 196 kPa, Dip of failure plane = 60°, Internal friction angle = 30°, Area over failure plane = 50 m\(^2\), Weight of hillslope material = 2000 tons (Round off to two decimal places)
