Please start from the instruction under the line below) DONE Start from here Professor instruction Email. Grade (please notice every part is extremely important to do very well) Abstract and pre-lab Questions Raw data Analysis (include calculation, Discussion, post-lab question) Attendance 30% 30% 30% 10% 1- Abstract –one paragraph- should be a concise summary of the lab. It should include the purpose of the experiment and what is being investigated, along with a brief, general description of the results and the extent to which the objectives of the lab were met. -Pre-lab questions if exist 2- Raw data should be tabulated based on the format indicated by instructor. 3- The analysis section includes any plot, graphs, calculations, ets. 4- The discussion is ideally a quantitative explanation of the results from the data analysis section, and their significance. This can be a good place to discuss shortcomings or gabs in the data collected. If the objectives were not met, it is appropriate to make brief mention of what would be done differently if there were a chance to repeat the lab My instructions Please follow the Professor instruction very carefully and divide the work exactly like what Prof explain preciously 1234- Abstract and Pre-lab questions Raw data The analysis The discussion This is the professor format DONNT add or remove any part just do these parts very well. Thank you

hi brother ... here is your lab ; kindly do contact me if any confusion..

Rotation and Torque Equilibrium of Rigid Bodies

Abstract:
In this experiment, principle of rotational equilibrium is drawn upon to realize a mass scale with the aid of
a balanced meter stick. Subsequently, with the help of this balanced meter stick, the following is
determined:
(i)
(ii)

centre of mass of meter stick
Mass of unknown object by applying a known torque

Moreover, comparison and investigation of theoretical calculated value of torque and force with respect to
experimentally determined value of the same torque and force will be undertaken.

Pre-lab questions:
Q. State a definition of Torque?
Ans: Torque refers to the tendency of force to rotate an object about an axis. When a force is
acting on a rigid body pivoted about an axis, the rigid body develops a tendency to rotate about
the axis. The tendency toward rotation is regarded as torque, τ.

Q. Give an equation for torqe.Define the terms in the equation.
Ans: The magnitude of the torque can be expressed as:
Torque ( )  F  r  F .r sin(  )
The torque is a result of a multiplication of force F and r sin(  ) (i.e. the perpendicular...
