Open the simulation and double check that the settings on your screen are the same as shown in the image below. In this simulation, a string is pulling on a block, dragging it so that it moves horizontally to the right. The string should be at a 30-degree angle with the horizontal, the mass of the box should be 2.5 kg, and the coefficient of kinetic friction should be 0.4 N Tension (N) 35 Mass (kg) 2.5 Theta 30 Start Coefficient of Static Friction 0.5 Pause Reset Coefficient of Kinetic Friction 0.4 n 30 mg a = 11 m/s? v = 0 m/s Determine the magnitude of force that the string needs to exert (tension) so that the block moves with an acceleration of 2.48 m/s^^2.||
Theory and Design for Mechanical Measurements
Measurement is a term that refers to analyzing a manufactured component regarding the degree of accuracy for dimensions, tolerances, geometric profile, roundness, flatness, smoothness, etc. Measurement always involves comparing the manufactured component or the prototype with a standard specimen whose dimensions and other parameters are assumed to be perfect and do not undergo changes with respect to time.Precisely in mechanical engineering the branch that deals with the application of scientific principles for measurements is known as metrology. The domain of metrology in general deals with various measurements like mechanical, chemical, thermodynamic, physical, and biological measurements. In mechanical engineering, the measurements are limited to mechanical specific such as length, mass, surface profile, flatness, roundness, viscosity, heat transfer, etc.
Basic principles of engineering metrology
Metrology is described as the science of measurement, precision, and accuracy. In other words, it is a method of measurement based on units and predefined standards.
Hypothesis: EF=ma , f=MkfN
Question: Make a judgment about whether or not your hypothesis (I used EF=ma , f=MkfN) can be rejected or if it is supported based on this experiment. Justify your judgment with evidence from this experiment. What assumptions did you make? Help me with this question please
