It would depend on how strong the weight lifter is.
Answer: It depends upon your definition of "work". Assuming the lifter put the barbell back exactly where and how it was at first, then there was no work done in the physics context. If you mean manual labor, then yes, some work was done.
You can infer that she is working on building up her strength.
The immense jungle cat squatted silently on the tree limb, patiently awaiting his next meal. The muscular weight-lifter then squatted in front of the huge barbell.
While just holding the weight on his shoulder, the weight lifter does no work! For work to be done, the mass must be moved through a distance … No Movement, No Work! (but don't tell that to a weight lifter …)
You can tell if you have a blown lifter by get someone to count of 10 seconds for you and you need to count how many times the noise happens in the 10 seconds and then multiply by 6. That should give you a number. Take that number and then compare it to your idle RPM's. If it's the same as your idle RPMs, then it's likely bottom end knocking. If it's half as fast as your RPMs - then it's valvetrain, like a lifter or an exhaust leak.You can tell if you have a blown lifter by get someone to count of 10 seconds for you and you need to count how many times the noise happens in the 10 seconds and then multiply by 6.
