Where direction designations R, V and A are recognized as suffixes for force components, F, this
represents the force component in the respective direction. The suffix R may be omitted, when
measuring direction is implied by the context.

2.5.2 Horizontal Mounting
In the majority of cases horizontal mounting is the most obvious and simplest solution. Stand,
mounting surface and shims (if required) are simple and cheap to make.
When calculating the force, the equations below must be used:
F
R
= T × (sin
α
+ sin
β
)
F
RT
= Tare
F
Rtot
= F
R
+ F
RT
= T × (sin
α
+ sin
β
) + Tare
F
V
= T × (cos
β
- cos
α
)
F
VT
= 0
F
Vtot
= F
V
+ F
VT
= T × (cos
β
- cos
α
) + 0 = T × (cos
β
- cos
α
)
where:
T = Strip tension
F
R
= Force component from strip tension in measurement direction, R
F
RT
= Force component from Tare in measurement direction, R
F
Rtot
= Total force in measurement direction, R
F
V
= Force component from strip tension in transverse direction, V
F
VT
= Force component from Tare in transverse direction, V
F
Vtot
= Total force in transverse direction, V
Tare = Force due to tare weight
α
= Deflection angle on one side of the roll relative the horizontal plane
β
= Deflection angle on the other side of the roll relative the horizontal plane
