you can lean against a wall because it's pushing back
I believe that the answer to this lies in the forces acting on the bike, namely the the frictional force, the turn itself is made by the wheels, which create friction sideways. The centripetal force acting in the turn is the friction, imagine a motorcycle driver that doesn't lean into the curve; because he doesn't lean, the friction is not strong enough to keep the driver from going in a straight line. However, when he leans, the static friction from the road increases, therefore the centripetal force increases. Note: There is an aspect of this question that also relates to Torque.
If the forces aren't balanced while sitting on a chair, the chair may tip over. For example, if you lean too far to one side or exert a greater force on one side of the chair, it can destabilize the chair and cause it to fall over. It's important to distribute your weight evenly to keep the forces balanced and prevent accidents.
Leaning backward goes against our natural instinct to maintain balance and stability. Our body's center of gravity is located near the front, making it easier for us to lean forward than backward. Additionally, our muscles are often more accustomed to supporting weight in a forward-facing position.
If you lean on a wall, the reaction would depend on the stability and strength of the wall. In general, the wall will support your weight and you will feel leaning against it. If the wall is unstable or weak, it may not hold your weight and could potentially collapse.
Trees on hillsides may lean due to uneven soil erosion, roots growing on one side, or wind direction. Gravity also plays a role in causing trees to lean downhill over time.
You're probably thinking of "to lean" as in "The cowboy was leaning against the fence".
No.

"Lean", I presume you mean "Just in Time" and not that all of the production employees are leaning against the wall because there is nothing for them to do... In lean production, you match your output to demand and keep less stock in the warehouse.
so he can lean against the wall
they lean against the closest thing thay can find and rub against it. simple!
Lean against the wall or a sturdy object for support and to give your body a break from standing or moving for a moment. This can help relieve pressure on your feet and legs and provide a moment of rest for your body.
lean lots of different size twigs against a tree then cover with bracken
Do you need to lean against the wall or can you do a freestanding handstand? A kiosk at the mall is a freestanding exhibit.
Lean against him, gently kiss the side of his neck, touch him gently anywhere, put his hand on your breast.
Lean-tos
sit-ups for your stomach press-ups for your arms and lean against a wall in the squat position for your legs :).
