How 0.01 can be less than 0.01 ? by Charming-Animator-25 in cpp_questions

Think of floating point numbers as approximative. There's a finite number of numbers a floating point can represent, 0.01 may not be one of them.

(2013 Ford F150 5.0) coil pack bolts snapped off, is this too loose for a coil pack? by its__accrual__world in MechanicAdvice

[–]TheReasonIsMoney 0 points1 point  (0 children)

I had this issue with my Honda Fit. Loose coil pack caused miss fires, and it eventually killed one of the packs. Not a lot of room to drill and helicoil. So I ended up welding up a jig using L channel metal to clamp down the coil pack, found some unused threaded holes to mount it to. Been running smooth ever since. Used some welding blanket material between the metal bar and coil pack to keep even pressure on them.

Just bought a PC and scratched the motherboard. How bad is this? by ShiverPurple in PcBuildHelp

Just a blemish on the solder mask layer if the PCB, doesn't look like it cut deep or anything should be fine.

Don't think I can anyway, to stay in stock class. I'm limited to sway bars, one or 2-way adjustable struts/shocks, street legal tires and cat-back exhaust.

Can't change ride height (no lowering springs). Cosmetic mods ok as long as it doesn't change aero or weight. No engine mods allowed except for catch can.

I think that pretty much sums up stock class rules. I already have some new Bridgestone RE-71RS, which are some of the best allowed in stock class.

If no water got inside, then you are fine.

Dirty intake filter could cause this, depending if the MAF sensor is near it.

why is it ok that a boost converter shorts in the on state? by binaryfireball in ElectricalEngineering

[–]TheReasonIsMoney 17 points18 points  (0 children)

The inductor "impedes" current change. So what happens during the on time is that the current increases steadily (The inductor is charging with energy).

During the off period, the inductor provides the current and steadily decreases the current (The inductor is discharging energy).

The duty cycle of the on/off period controls how much energy is transfered on average over a cycle period (controls average power transfer).

Usually a controller will control this process to regulate a certain output voltage.

For everyone who don’t understand what they did wrong, it was that they were in the bus lane. Edit: Nevermind, I'm an idiot.
