A fin of diameter d W 0.3 cm, length L = 2 cm, and conductivity k = 138 is dissipating heat m. K from a surface at 100 °C. The ambient air is at T. 20 °C and the convection heat transfer coefficient is h = 10 2. Using the adiabatic fin method equations (fin with negligible heat loss at m2.K the tip) along with the corrected fin length, Lc, find the rate of heat dissipated by the fin (in Watts).

On a average work day more than work place firs are reorted

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
