Unsupported Load for Cores Solution

Follow our step by step solution on how to calculate Unsupported Load for Cores?

FIRST Step Consider the formula

UL = F b - c \cdot A

Next Step Substitute values of Variables

∴

UL = 1500N - 350N/mm² \cdot 4E-6m²

Next Step Convert Units

∴

UL = 1500N - 3.5E+8Pa \cdot 4E-6m²

Next Step Prepare to Evaluate

∴

UL = 1500 - 3.5E+8 \cdot 4E-6

LAST Step Evaluate

∴

UL = 100N

Formulas to find Unsupported Load

Buoyant Force

Buoyant Force is the upward force exerted by any fluid upon a body placed in it.

Symbol: F_b

Measurement: ForceUnit: N

Note: Value can be positive or negative.

Formulas to find Buoyant Force

Empirical Constant

Empirical Constant is the constant used in an empirical relation. It can vary depending on the specific casting material and they are derived from data obtained from actual casting operations.

Symbol: c

Measurement: PressureUnit: N/mm²

Note: Value should be between 349 to 351.

Core Print Area

Core Print Area is the area of that part of the mould which supports the weight of core used in casting.

Symbol: A

Measurement: AreaUnit: m²

Note: Value should be greater than 0.

Go Buoyant Force on Cores

F b = 9.81 \cdot V c \cdot (ρ cm - ρ c)

Go Volume of Core

V c = \frac{F b}{9.81 \cdot (ρ cm - ρ c)}

Go Density of Core Material

ρ c = ρ cm - \frac{F b}{V c \cdot [g]}

Go Density of Molten Metal

ρ cm = \frac{F b}{V c \cdot 9.81} + ρ c

How to Evaluate Unsupported Load for Cores?

Unsupported Load for Cores evaluator uses Unsupported Load = Buoyant Force-Empirical Constant*Core Print Area to evaluate the Unsupported Load, The Unsupported load for cores is to be defined in order to calculate the required chaplet area a. It is the load which is not supported by anything and thus has to be supported by chaplets. Unsupported Load is denoted by UL symbol.

How to evaluate Unsupported Load for Cores using this online evaluator? To use this online evaluator for Unsupported Load for Cores, enter Buoyant Force (F_b), Empirical Constant (c) & Core Print Area (A) and hit the calculate button.
