Question

A helical compression spring is made of 5mm diameter hard-drawn wire. Determine the torsional yield strength of the wire in MPa.

Answer #1

The solution of the problem is in the screenshot attached below.

A helical compression spring is made of hard‐drawn steel wire
0.080‐in in diameter, has an outside diameter of 0.880 in, and a
pitch of 0.040 in. The ends are plain and ground, and there are 8
total coils. If the spring is supported by two parallel plates, is
it possible that the spring can buckle in service? Support your
response quantitatively.

A helical compression spring is made of 3mm diameter music wire.
The outside coil diameter of the spring is 14mm. Find the static
load of the spring in N if the torsional yield stress is
3.7GPa.

A helical compression spring is made of 302 stainless steel
wire. The outside coil diameter of the spring is 33.2 mm. The wire
diamter is 2.8 mm. The ends are plain and ground, and there are
total of 8.5 turns. Determine the deflection of the spring when it
is subjected to a compression force of 10 N. In this condition, wil
the stress generated in the spring be beyond the maximum allowable
torsional stress?

A helical compression spring is made from music wire that is
1.04 mm in diameter and has an outer coil diameter of 13.74 mm with
a free length of 50.8 mm and 10 total coils with plain ends.
What is the solid length Ls?
What is the spring rate k in N/m ?
If the spring rate is 1000 N/m what is the maximum shear stress,
tau , in the wire when the spring is compressed 25.4 mm from its...

A close-coiled helical spring has a wire diameter of 2.5 mm and
a mean coil diameter of 4Omm. The
spring is subjected to a combined axial load of 60N and a torque
acting about the axis of the spring. determine the
maximum permissible torque if (a) the material is brittle and
ultimate failure is to beavoided, the criterion of failure is
the maximum tensile stress, and the ultimate tensile stress is 1.2
GN/m2, (b) the material is ductile and failure...

2. Use hard-drawn 0.075” diameter wire to make a spring with
closed ends, a spring index of 10,
and 12 total coils. Use a load factor of safety of 1.05 and make
the free length 3.0 inches.
a) What is the spring rate?
b) What is the critical length for absolute stability?
c) What is the maximum suggested load?
d) What is the force to close to solid, Fs?
e) What is the critical frequency?
f) What is the factor...

A helical spring is to provide a minimum force of 600 N at
installation and have a working deflection of 25 mm. The spring
rate is 13 N/mm. The coil must fit in a 55 mm diameter hole with at
least 2.5 mm clearance. Use a 6.5 mm diameter unpeened music wire
with squared and ground ends. Using 15% clash allowance, find:-
i. spring constant
ii. free length of the spring.
iii. the ‘solid’ length of the spring
iv. Draw...

A round steel rod made of structural steel,with yield strength
of 48ksi and E=30Mpsi, is to be used as a column with pi-pin
connection(C=1), centrally loaded with 10 kips; N = 3 . Determine
the diameter for L = 25 in. Determine also if long or short
column.
