Answer:
a) 0.35 W
b) 5.25 W
Explanation:
Given that
Width of the chip, W = 5 mm
The environment temperature, T(∞) = 15° C
Surface temperature, T(s) = 85° C
The initial convection heat coefficient, h1 = 200 W/m².K
The final convection heat coefficient, h2 = 3000 W/m².K

Answer:
Overall ideal mechanical advantage of the machine = 40
Explanation:
Given:
Ideal mechanical advantage of three machine = 2, 4, 5
Find:
Overall ideal mechanical advantage of the machine
Computation:
Overall ideal mechanical advantage of the machine = 2 × 4× 5
Overall ideal mechanical advantage of the machine = 40
Answer:
Mechanical Advantage Formula
The efficiency of a machine is equal to the ratio of its output to its input. It is also equal to the ratio of the actual and theoretical MAs. But, it does not mean that low-efficiency machines are of limited use. An automobile jack, for example, have to overcome a great deal of friction and therefore it has low efficiency. But still, it is extremely valuable because small effort can be applied to lift a great weight.
Also, in another way the mechanical advantage is the force generated by a machine to the force applied to it which is applied in assessing the performance of the machine.
The mechanical advantage formula is:
MA = FBFA
Explanation:
MAmechanical advantageFBthe force of the object
FAthe effort to overcome the force
