Why does bicycle tire stay upright after slight push?
When a bike leans, the gyroscopic effect tends to steer the handlebars in the direction of the lean, bringing the wheels back under the bicycle and helping to keep it upright. When given a good push, the experimental bike still coasts and balances successfully if it is going fast enough (more than about 5 mph).
Why do cyclists zig zag?
A zigzag pattern increases the length of the hill, lowering the rate of climb. It is easier to go up a long hill with a shallow slope than a short steep one.
Why is it easier to climb a mountain via a zigzag?
Zigzag path is easier to climb the mountain because work is doing along a longer path and gravitational pull for each step is less for longer distance so, it requires less force at any instant. similarly when we climb on straight path, the distance is shortest gravitational pull is more so, i it’s difficult to climb.
What can slow down a bike?
If you try to shift and your bike doesn’t find the gear you were hoping for right when you need it, it’ll slow you down. Over time, cables stretch, derailleur springs wear and the teeth on your cassette eventually become round, so a regular tune-up is necessary to keep your bike shifting smoothly and on time.
What makes a car accident a sideswipe accident?
While distracted with answering your phone, you fail to stop at the stop sign and strike the side of a vehicle in the intersection that had the right-of-way. A sideswipe accident is one where two vehicles that are traveling in the same direction make contact with one another while moving.
What causes a car to pull in the opposite direction?
If the car pulls in the opposite direction after you’ve done this, you’ve found tire trouble. Check your tires’ tread-wear patterns. For example, if a front tire’s tread tends to disappear along the outboard edge, it’s likely that the camber setting at that corner is too positive, and any pull probably will be toward that side.
What causes steering wheel to wander when driving?
Look down on them while your helper holds the brakes and shifts from Drive to Reverse and back. You’ll see and hear excessive movement. LOOSE: Minor adjustment to the clearance of a high-mileage steering box can tighten up the steering. LOOSER: Worn tie-rod ends let the wheels wander, making steering vague.
