What features of knee joint structure help minimize friction between the thigh bone and leg bone?

The cartilage and fiberous tissue create an impact zone and the fatty materials there lubricate the mechanical hinge of the bones. The joint structure itself however holds no friction reduction, it is the secondary structure of soft tissues that do all of the protection.

What is a bursa?
A bursa is a sac filled with fluid to protect the tendons (plural bursae).A bursa is an expansion of synovial membrane that is found at sites of potential friction, ie. between your Achilles tendon and your calcaneus (heel bone).Bursae are lubricated on their inner walls by synovial fluid. By rolling between two structures, bursae keep friction to a minimum and prevent damage.
What prevents friction between the lungs and the ribs when breathing?
the flesh and padding muscles in between each
Differentiate the four types of protein structure?
There are four types of protein structure. These include primary structure, secondary structure, tertiary structure, and quaternary structure. Primary structure is the amino acid sequence. Secondary structure is the shape of the molecule. Tertiary structure is the interaction between groups. Quaternary structure is the interactions between protein subunits.
What is the structure located between the centrioles of a cell?
The spindle is the structure in between the centrioles.
Compare the structure function and common body locations of bursae and tendon sheaths?
They act as "ball bearings" to reduce friction between bones. Bursae are flattened fibrous sacs lined with synovial membrane and are commonly found where ligaments, muscles, bones, or tendon rub together. A tendon sheath is essential an elongated Bursae that completely wraps around tendons subjected to friction.
What are the different ways the lassen or minimize the effect of friction?
By reducing the contact surface area of the object and by applying the lubricant between the two contact surfaces lassens or minimizes the effect of friction.
Why there should be a gap between the load applied to the structure and the factored load on the design?
to minimize over load
Which is the best lubricant to reduce friction between two surfaces?
the best lubricant to reduce friction between two surfaces is to put butter or olive oil on to make the surfaces slippery o
What is the friction between moving particles called?
The friction between moving particles is called friction.
Does overpolishing of surfaces increase the friction between them?
No it does not. It will actually reduce the friction between them.
What are some situations where friction is good and some some where friction is bad?
In situations where you want to create heat or dissipate kinetic energy, friction is usually a good thing. Friction when rubbing your hands together creates heat, which you appreciate, and friction between your brake pad and brake disc slows down your car, which is also a good thing. In situations where you want to maintain kinetic energy or minimize heat, friction is usually bad. Air friction slows down a glider, limiting its range, and mechanical friction in a car rolling on a flat surface causes it to stop without the brakes being applied.
The friction between objects that are moving is?
Air friction.
Why is it important for a bursa to be located between movable bones?
A bursa acts as a cushioning and lubricating structure that reduces friction and allows for smooth movement between bones. Having a bursa between movable bones helps to prevent wear and tear on the joint surfaces, decreasing the risk of pain, inflammation, and injury.
What does friction between objects produce?
Friction between two objects produces heat.
How do cars use friction to stop?
Friction between the brake pad/lining and the rotor/drum and friction between the tyre and the road.
Do lubricants help to reduce friction?
Lubricating fluids have a sliding lattice structure which helps the atoms in the lattice to slide over each other and thus reduce the friction in the bodies in which they are applied. The relative sliding between the layers helps in lubrication.
What is the friction that exits between a surface sliding on another surface is called?
If the two surfaces are moving relative to each other, then the friction between them is Kinetic Friction. Prior to the surfaces moving there was Static Friction between them.
