ELI5: Why is lifting weights with long arms heavier than with short
It deoends on how you''re lifting the weights, but usually the shoulder or the elbow will act as a pivot when lifting dumbbells. This is because when a force is applied along a rod (arm/forearm) that is fixed to a pivot (shoulder/elbow), the horizontal distance between the pivot and where the force is applied acts as a sort of multiplier, which is strongest when the arm is horizontal (as
Why Do Jumping Spiders Raise Their Arms?
When it comes to the speed of their movements, jumping spiders are slow. Unlike humans, spiders do not have any special muscles that are designed to propel them. However, they do have a mechanism that increases blood flow to their legs. This increases the length of the legs and allows them to be able to extend them when necessary.

6 FAQs about [What does the length of the solar powered jumping arm mean ]
Does arm swing affect effective energy in vertical jumping?
The force-velocity relationship has been put forward to explain the increase in hip joint work. Nevertheless, the efficacy ratio, muscle shortening length, and active state might be parameters that affect the effective energy and then VJH. The purpose of this study was to evaluate the influence of arm swing on effective energy in vertical jumping.
How does a jump simulation work?
Simulations start from a balanced initial posture and end at jump takeoff. Jump height is maximized by finding the optimal combination of joint activation timings. Arm motion enhances jumping performance by increasing mass center height and vertical takeoff velocity.
Does limb length affect vertical jump ability?
Long segments may create a challenge to generate angular velocity for vertical jumping. The fact that truncated foot length (females) and tibial length (males) were negatively correlated with jump height suggest that limb length may influence vertical jump ability. These findings contradict earlier research.
Does arm motion improve jumping performance?
In conclusion, simulations have confirmed that arm motion can enhance jumping performance and the increased takeoff vertical velocity contributes nearly 2/3 to the increased height. The arms also cause an earlier onset of hip torque and lengthen ground contact duration.
