4 (a) State Hooke's Law.[1](b) A spring is compressed by applying a force. The variation with compression x of the force F is shown in Fig. 4.1.60F/N4020001020304050x/mm Fig. 4.1(i) Calculate the spring constant.spring constant ==... m^(-1) 1](ii) Show that the work done...
might these values be justified, in what ways not?in November
Hooke’s Law is a representation of linear elastic deformation. Elastic means that the spring will return to its original form once the outside force (the mass) is removed. Linear describes the relationship between the force and the displacement. The fact that the spring constant is a constant...
Assuming the spring obeys Hooke's law, the increase in force on the piston required to compress the spring an additional amount \Delta x, is given by \Delta F = F − F0 = (P − P0)A = k(\Delta x), w...
Step 2:Use the equationa=kxmto calculate the magnitude of the spring's acceleration. What is Hooke's Law and Hooke's Law Equation? Hooke's Law:The law states that the force applied to compress or stretch spring is directly proportional to the distance x it is displaced from ...
A certain spring that obeys Hooke’s law is stretched by an external agent. The work done in stretching the spring by 10cm is 4J. How much additional work is required to stretch the spring an additional 10cm? A、4J B、8J C、12J D、16J
How much is the energy stored in Hooke's law spring increased when its stretch is increased from 8 cm to 16 cm? Why is it 300%? Elastic Potential Energy of Spring: The elastic potential energy stored in the spring is given by the ...
Physical Science STEM GO Category: Force & Motion product Overview: A set of 5 springs with different spring constant (k)- they stretch by 2cm with a load of 0.5N, 1N, 2N, 3N and 5N respectively. Pre-stress has been removed for accurate results. With a hook to support weight hanger ...
