A horizontal force F is applied at the top of an equilateral triangular block having mass m. The minimum coefficient of friction required to topple the block before translation is `mu `,find `100 mu ? ( sqrt(3) = 1.74)`

Text Solution

Verified by Experts

The correct Answer is:
58
For toppling
`F.(a sqrt(3))/(2) =mg ,(a)/(2) , " " F=(mg)/(sqrt(3))`
for not sliding
` F le mu mg , (mg )/(sqrt(3)) le mu mg `
` mu ge (1)/( sqrt(3))`
