landslide load (weight of the overburden) or a steepening slope would be considered components of which factor?
resisting force
driving force
question 28
2 pts
you buy a house which is at the base of this hillside and after looking at some past landslide maps it appears that \maybe\ the hill has failed in the past. calculating the driving and resisting forces, the former amounts to 600,500,100 and the latter to 595,800,500. is the factor of safety high enough to consider this slope stable?
unable to determine
no
yes

Explanation:

Step1: Calculate the Factor of Safety

The formula for the Factor of Safety ($FS$) is $FS=\frac{\text{Resisting Force}}{\text{Driving Force}}$.
Given that the driving force ($DF$) = $600500100$ and the resisting force ($RF$) = $595800500$.
So, $FS=\frac{595800500}{600500100}\approx0.992$.

Step2: Determine Stability

A slope is considered stable if $FS\geq1$. Since $0.992 < 1$.

Answer:

No
