 The mechanical dimensions are given by L = 0.0175m, B = 0.015m, s = 0.004m. The upper limit can be calculated as follows: The mechanical dimensions are given by L = 0.0175m, B = 0.015m, s = 0.004m. The upper limit can be calculated as follows:
-\\  + 
-  //(1) tan(β) = sin(β) / cos(β) = (B - y) / L// \\ +  (1) tan(β) = sin(β) / cos(β) = (B - y) / L 
-  //(2) cos(β) = s / y// \\ +  (2) cos(β) = s / y 
-\\ + 
-Substitute (2) into (1) to get: \\ +Substitute (2) into (1) to get: 
-  //(3) L*sin(β)-B*cos(β)=-s// \\ +  (3) L * sin(β) - B * cos(β) = -s
