1)In this experiment, the weights are added sequentially (ON,5N, 10N,15N,20N) for the first spin, the position of the middle pulley and the position of the dynamometer are in the same unit (i. e. on one line) a) Calculate the tensile values for T1 and T2 in this case. 2)The dynamometer is moved one unit up and the center pulley position will decrease. Note One unit is 0.5cm. a)Calculate the mechanical work on the pulley from the law. (Work on pulley=F*S=F*Str) b)Calculate the mechanical work on a dynamometer from the law. (Work on dynamometer-F*S=F*Sm) Discussion 1) Draw on graph paper a diagram of the relationship between the weight on the pulley and the value of tension T1 and T2. 2) Draw on graph paper a diagram of the relationship between displacement on the pulley and displacement on the dynamometer. 3) Discuss the results​

unlike the threaded fasteners which are used to clamp the machine members, power screws are used to transmit power. common applications of power screws are: screw jacks: to lift weight. lead screw of lathe: for axial movement of tool and its precise positioning.

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
