We see in the figure above that weight of #60# tons acts in the vertically downwards direction.
The monolith tend to slide down the causeway due to #sintheta# component of weight acting along the slope.

This is the force required to hold the monolith.

As in the figure this component#=60xxsin2.3^@#

#=2.41\ "tons"#, rounded to two decimal places.
