A valve spring pressure test shows a reading of 74 psi. A parts manual says that the
spring should test at 80psi±10%. Is this spring within tolerance?

Respuesta :

Step-by-step explanation:

80 psi  minus 10% =   80 - 8 = 72 PSI

80 PSI PLUS 10% = 80 + 8 = 88 PSI

If the spring measures between   72  and 88 psi  (inclusive), it is within spec

74 PSI is within the tolerance
