TEXT ANSWER In order to make a video for physics class, Sergei used concrete blocks to create static equilibrium to balance himself on a board. Sergei planned to sit 2.0 m from the pivot point and place the blocks 4.0 m from the pivot point on the opposite side. Sergei's mass was 100.0 kg. If each concrete block had a mass of 10 kg, how many blocks did Sergei need to place the system in static equilibrium? Show your work.

Center of Gravity of a system

The centre of gravity is a property that is based on the geometry of a rigid body or any particle. It is described as an equilibrium point or a hypothetical location where the total weight of the body is concentrated.

Question

TEXT ANSWER
In order to make a video for physics class, Sergei used concrete blocks
to create static equilibrium to balance himself on a board. Sergei
planned to sit 2.0 m from the pivot point and place the blocks 4.0 m
from the pivot point on the opposite side. Sergei's mass was 100.0 kg.
If each concrete block had a mass of 10 kg, how many blocks did
Sergei need to place the system in static equilibrium?

This figure shows a person preparing to do a pushup. Calculate the back extensor force (Fm) required to keep the trunk in the static position as shown. Report Fm, in units of N, to 0 decimal points (e.g. 101 N). Report only positive values (i.e. the absolute value). You are allowed an error margin of +/- 10 N from the exact correct answer. The spine and back extensor muscle (Fm) are aligned horizontally with the floor. The ground reaction force (GRF) under the hand is aligned vertically. You only need to consider the weight of the trunk (disregard the head and arms). Here is information you may need to solve this problem: • The GRF is 195 N. • The GRF has a moment arm of 0.4 m relative to the vertebra axis of rotation. • The weight of the trunk is 303 N. • W trunk has a moment arm of 0.29 m relative to the vertebra axis of rotation. • Fm has a moment arm of 0.06 m relative to the vertebra axis of rotation.
