A copper piece of mass 10g is suspended by a vertical spring. Thespring elongates 1cm over its natural length to keep the piece in equilibrium. A beaker containing water is now placed below the piece so as to immerse it completely in water. Find the elongation of the string.
Density of copper is 9000 kg/m^3
g = 10 m/s^2
SEE ATTACHMENT #1 for a diagram of thesprings and both arrangements.
Spring A has forceconstant kA= 60 nt/m. Spring B has forceconstant kB= 40 nt/m.
The two springs attached end to end form a series combination with forceconstant Ks.
The two springs attached side by side so that a force applied to the ends stretches bo
A 10-cm-long spring is attached to the ceiling. When a 2.0 kg mass is hung from it, thespring stretches to a length of 15 cm.
(a) What is thespringconstant k?
(b) How long is thespring when a 3.0 kg mass is suspended from it?
1. If a certain spring stretches 8.93072 cm when a load of 18.6372 N is suspended from it, how much will thespring stretch if it is cut in half and when 30.2799 N is suspended from it? Answer in units of cm
2.A certain spring stretches 4.5 cm when it supports a mass of 0.77 kg. If the elastic limit is not reached, how far
Question: When an object weighing 50 N is hung from a vertical spring, it stretches 20 cm. Calculate thespring's elastic constant. If the 50 N load were replaced with a 80 N weight, how far would thespring stretch?
Two springs with the same unstretched length, but different forceconstants and are attached to a block with mass on a level, frictionless surface. Calculate the effective forceconstant in each of the three cases depicted in the figure.
a). Express your answer in terms of the variables k1, m, k2
k_eff -c =
b) An object
