La aleación de aluminio no forma parte de la fabricación de cascos de seguridad. (Opción correcta: E)
En esta pregunta debemos determinar que materiales son apropiados para la producción masiva de cascos de seguridad para luego determinar la opción inapropiada. El material de casco de seguridad debe cumplir las siguientes características:
DuctilidadMaleabilidadFabricabilidadElevada resistenciaResilienciaElevada razón de resistencia a pesoPoca conductividad térmicaPoca conductividad eléctricaEsto se cumple con materiales poliméricos o materiales compuestos de sustrato cerámico y refuerzo polimérico de tipo termoplástico. Estos materiales tienen la ventaja frente al aluminio de tener menor peso, mayor resistencia mecánica y mayores razones de resistencia a peso. Pese a tener mayores costes de manufactura, tienen similar fabricabilidad y satisfacen los requisitos de seguridad.
Otro factor crucial es el hecho de que el aluminio es un conductor térmico y eléctrico, mientras los materiales poliméricos y compuestos de sustrato cerámico y refuerzo polimérico no lo son.
En consecuencia, la aleación de aluminio no forma parte de la fabricación de cascos de seguridad. (Opción correcta: E)

A firm produces and sells a product with a contribution margin of $32 per unit. The firm is presently selling 90,000 units and earning $240,000 in after-tax income. Taxes are $80,000 at a 25% tax rate. If the firm desires to increase its after-tax income to $300,000, how many more units must it sell?
9514 1404 393
Answer:
2500 more units
Explanation:
The after-tax contribution margin per unit is ...
$32 - 25%×$32 = $32 -8 = $24
To increase the after-tax income from $240,000 to $300,000, an increase of ...
$300,000 -240,000 = $60,000
is required. If each unit contributes $24 in after-tax income, then the number of additional units required is ...
$60,000/($24/unit) = 2500 units
The firm must sell 2500 more units to make the desired increase in after-tax income.
