The resultant force will be
twice the applied force.In a lever, the total distance from the applied force to the fulcrum is
the effort arm. And, the distance between load and the fulcrum is
the load arm.
When the effort arm is two times the load arm, it means the resultant force will be twice the applied force.
Because, Force = displacement × speed
26.676 × 10³ kg is the weight of the aluminum rod.
<h3>To calculate specific weight:</h3>
Given:
Length of cylindrical rod (h) = 45 cm
Diameter of a cylindrical rod = 4.53 cm
Radius of a cylindrical rod (r) = 2.3 cm
The density = 3.7*10^3kg/m^3
Volume of a cylindrical rod = πr²h
= 3.14× (2.3)² × 45
= 747.89 cm
= 7.4789 m
To find weight ;
ρ = ; ρ = Density
Mass = ρ × Volume
= 3.7 × 7.48 × 10³
=27.676 × 10³ kg
Therefore, the weight of the aluminum rod is 27.676 × 10³ kg.

Answer:
In physics, motion is the change in the position of an object over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. The motion of a body is observed by attaching a frame of reference to an observer and measuring the change in position of the body relative to that frame.
