Homework 3
The position of a slider-block linkage is required to be 
m when 
. A failure
occurs if the actual position 
is outside the tolerance range 
m. The design variables are
independent and follow normal distributions of 
, 
. Since uncertainty exists in the
measurement of 
, the angle also follows a normal
distribution with 
. The measurement uncertainty is
independent of that in the mechanism dimensions. Use the First Order Second
Moment (FOSM) method to calculate the probability of failure.
