Answer:
the work done by the linear spring will be equal to 23.04 k J
Explanation:
given,
k = 32 k N /m
deflected spring = 120 cm
= 1.2 m
work done by spring can be calculate as
=
=
= 23.04 k J
hence, the work done by the linear spring will be equal to 23.04 k J
Answer:
The explanations are provided below.
Explanation:
a) The accelerated thermal cycling test is a test that is performed to evaluate the fatigue strength of electronic solder connections. The glass transition temperature given as is a frequently used parameter to test the degree of cure of an epoxy encapsulant.
b) The Coefficient of Thermal Expansion of Encapsulant
This is an important parameter to prevent crackling. Crackling occurs when a joint is subjcted to high temperatures during reflow soldering. Thus, the property is important in determining the limits of the joint.
