What class of lever is in leg extensions?
THIRD Class
Is your leg a lever?
yes
What class of lever is being used wh abduction of the hip occurs?
The gluteus medius and minimus abduct the hip joint. When you are standing on the right foot, the body tends to till towards the left side. The right gluteus med and min abduct to pull the body towards the right side. This way, our balance is maintained. In this situation, (1) it is the pelvis rather than the thigh that is abducted; (this causes the trunk to flex towards the right); (2) the pivot is the right hip joint; (3) the force is the outward and downward pull of the right gluteal muscles on the pelvis; and (4) the load is the body weight. It is a Class 1 lever mechanism. (An illustration in a general Anatomical Atlas from a popular Germany publisher appears wrong.) When you are walking, the right gluteus med and min abduct to raise your right foot. In this situation, (1) the pivot is again the right hip joint; (2) the force is the outward and upward pull on the thigh; (3) the load is the weight of the right thigh, leg and foot. The insertion of the muscles are very near the hip joint, whereas the centre of gravity of the lower limb should be farther await from it. It is presumably a Class 3 lever mechanism.

How might a blood clot in your upper leg affect your body?
Impedes blood flow to & from leg ... so you might lose that leg. Also, if the clot breaks loose it can interfere with systemic or pulmonary circulation - in which case you might die.
A person's leg meas-ures 42 cm an average leg diameter 13cm and a potential difference of 0.70 V causes a current of 1.7 mA . What are the fractions of muscle and fat in the leg?
Well, in order to get a better estimate, we would need to know the sex of the person and their BMI. It is crucial for trying to figure out the ratio of muscle and fat in the leg.
What class of lever is in leg extensions?
THIRD Class
Is a leg kicking ball is example of first class lever?
third class lever. Load/Resistance is the ball fulcrum = hip & knee
Is your leg a lever?
yes
What is an example of a 2nd class lever?
A few examples are...... nutcrackers papercutter a wheelbarrel
How do you do leg presses?
You press your leg up
What kind of a simple machine is it when you kick something?
A lever, the leg acts as the lever and the ball acts as the load.
How can you shift your car from park to drive in a 1995 camaro?
Are you kidding me??!! Press the brake pedal down and hold it there. Next, grab the shifter lever to the right of your leg. Depress the little button on the lever, and move the lever to the desired gear. Next, take your left hand, pull the pistol out of the glove compartment, and shoot yourself in the head!
Are there inherent DANGERS in leg press?
To much force applied to the leg press has been known to flatten legs.
Is the hip joint an example of a first class lever?
Hip joint act as both first class lever and third class lever, as per which work we are doing and which muscles are working on hip for that particular work. When we stand in single leg, then force exerted by hip abductor muscles is "power " and neck of femur is "power arm"; centre of femoral head is "fulcrum"; and body weight is "load" and centre of head of femur to symphysis pubis is "load arm". So here hip joint work as first class lever. But when we do straight leg raising (SLR), then "power" is exerted mostly by the hip flexor muscles [comprise the psoas major (PM), iliacus (IL), rectus femoris (RF), sartorius (SAR), adductor longus (AL), and tensor fasciae latae (TFL)] in between hip joint and knee joint (here length "power arm" is different for different muscles, but we can assume that "power arm" is hip joint to knee joint. Here "load" is weight of leg and "load arm" is hip joint to foot. So in this case, hip joint work as third class lever.
Are there benefits using a leg press machine?
Using a leg press machine is great exercise. There are many benefits to using the leg press machine such as increased muscle tone, decreased fat, and just general toning.
What is a second class lever?
A Class 2 lever has the load in-between the effort and the fulcrum. An example is a wheelbarrow, Effort is at the handles, the wheel is the fulcrum, and load is the weight carried on the wheelbarrow.
Is the leg press considered transverse plane?
No
