A 12000 W crane can lift a box 52 m in 15 secWhat is the mass of the box? I just have no idea where to start, even though it seems easy enoughThank you!
Even assuming your information is correct, I wouldn't risk it because I bet the toaster oven is not calibrated carefully enough to stay under that 451 temp.
You should not have to worry about cross contamination1the rack will not be a good place for bacteria to grow2The heat in the oven will kill any bacteria that does begin to growThe residual heat in the oven after you remove food will dry out the surrounding area making bacteria growth almost impossibleI would suggest you get some disposable foil trays to bake or cook on only because it is difficult to clean the racks and you will develop a build up of carbon deposits from burned on grease and some residual foodBut again the food will be in no way a good for harboring bacteria.
The equation is P F x D divided by t P 12000 w F m x g (The force is the weight) d 52 m t 15 s g 9.8 put m x g in for F and we get P m x g x d / t Solve for m (P x t) / (g x d) Put in the numbers m 12000 x 15 / (9.8 x 52) 353 kg
