Prove the design criteria and Grashof criteria for a double-rocker 4-bar mechanism. Design criterion for double-rocker: L2 = Lmin. Grashof criteria: Lmin + Lmax < La + Lb After you’ve proven that Lmin = L2 you should be able to identify or create (from your 6 triangle inequalities) three expressions that fit the Grashof criteria, one for each possible Lmax.

answer:

gon freecss

explanation:

I would say 47 or if u use a yard it would be 69 seconds! Happy braining! Also Nina is a god breian!

Explanation:

A Carnot heat engine receives heat from a reservoir at 900$^\circ{}$C at a rate of 800 kJ/min and rejects the waste heat to the ambient air at 27$^\circ{}$C. The entire work output of the heat engine is used to drive a refrigerator that removes heat from the refrigerated space at -5$^\circ{}$C and transfers it to the same ambient air at 27$^\circ{}$C. Determine (a) the maximum rate of heat removal from the refrigerated space and (b) the total rate of heat rejection to the ambient air. Answers: (a) 4982 kJ/min, (b) 5782 kJ/min
