800D INSTALLATION
EXAMPLE:
A truck frame of 110,000 psi
(758 MPa) yield strength steel has
the following dimensions: 3/8 in
(9.65 mm) thick, 3 in (76.2 mm)
flanges and is 10.25 in (260 mm)
deep. To find the frame section
modulus:
1. From Table A, 3/8 in (9.65 mm) thickness, W (width) = 3
in (76.2 mm), D (depth) = 10 in (254 mm) section
modulus = 15.4 in
3
(252 cm
3
).
2. From Table A, 3/8 in (9.65 mm) thickness, W = 3 in (76.2
mm), D = 11 in (279 mm), Section Modulus = 17.7 in
3
(290 cm
3
).
3. Interpolating between the two values:
10 in (254 mm) deep channel
= 15.4 in
3
(252 cm
3
)
11 in (279 mm) deep channel
= 17.7 in
3
(290 cm
3
)
10.5 in (267 mm) deep channel
4. Now interpolate between a 10 in (254 mm) deep channel
and a 10.5 in (267 mm) deep channel to get the section
modulus of a 10.25 in (260 mm) deep channel.
10 in (254 mm) deep channel
= 15.4 in
3
(252 cm
3
)
10.5 in (267 mm) deep channel
= 16.55 in
3
(271 cm
3
)
10.25 in (260 mm) deep channel
A 3/8 in (9.65 mm) x 3 in (76.2 mm) x 10.25 in (260 mm)
truck frame has a 15.98 in
3
(262 cm
3
) Section Modulus
and RBM of 110,000 psi x 15.98 in
3
= 1,757,800 lb-in
(758 MPa x 262 cm
3
= 198,596 Nm)
5. 15.98 in
3
(262 cm
3
) Section Modulus, 110,000 psi (758
MPa) steel is adequate for a standard mount with a
torsion box.
