Questions within the problem domain of mechanical engineering. Mechanical Engineering can be a broad field; consider choosing more specific tags if they apply.

A solid cylinder with a protrusion like a cam if positioned such that the rolling down starts from the inclined tip of the cam will go down faster. The cam should be formed sharp so as not to change t …

F= m.a, it all depends on what acceleration you pull it with. So 20k/1500= 13.33 ft/s^2 roughly 40% of gravity acceleration. Use 60% of that as a conservative number. You could pull hypothetically unl …

No, if you hold the sun gear the carrier will turn at slower speed than the ring gear. You could have a setting where the ring gear is turning at the same speed as the input speed but then the carrie …
Assuming you want to use this as a teaching model, because I don't know if they are certified, you can have the lateral deviation indicator's motor connected trough something like these 2-3 wire rotar …
you can use a small spring loaded roller for window shade. They cost in the range of \$20 and many hardware stores custom cut them down to something like 6 inches. You can remove the shade and wind yo …
The Anything path is a circle with G at its center. So in that reference frame $$x= \sqrt{1-y^2}$$ But G is turning with its $$X_p = \sqrt{1-Y^2_p}$$ you have to transfer the X1 and Y1 to new …

to calculate the stress, you divide load by the surface area of your section be it a wire or rod or square bar. Remember $$\sigma = \frac{F}{Area}$$ But if you want to graph a stress/strain curve, …

let's call the cross section width B, base and its height H. And assume the length of the section supported by the wall L1 and the short elbow L2 and call the load P. the deflection at the end of L2 …

Speed of a ship and power demand and fuel consumption have to do with many factors. They are roughly enumerated as follows. Ship's engine power and draft versus speed curve. Seas' conditions: draf …
It can be a big challenge. Definitely is much smaller than standard, 9 meters which is approximately 30 feet, square turning area by our city code. Backing into gate may be a bit easier. Try on a op …
When a car makes a turn with a radius of R it is subject to an acceleration force, vector, called centripetal force $$F=m V^2/R$$ this force is applied to the center of gravity of the car and is dir …
