Answer:
45.3 MN
Explanation:
The forging force at the end of the stroke is given by
F = Y.π.r².[1 + (2μr/3h)]
The final height, h is given as h = 100/2
h = 50 mm
Next, we find the final radius by applying the volume constancy law
volumes before deformation = volumes after deformation
π * 75² * 2 * 100 = π * r² * 2 * 50
75² * 2 = r²
r² = 11250
r = √11250
r = 106 mm
E = In(100/50)
E = 0.69
From the graph flow, we find that Y = 1000 MPa, and thus, we apply the formula
F = Y.π.r².[1 + (2μr/3h)]
F = 1000 * 3.142 * 0.106² * [1 + (2 * 0.2 * 0.106/ 3 * 0.05)]
F = 35.3 * [1 + 0.2826]
F = 35.3 * 1.2826
F = 45.3 MN
Answer:
Un motor de paso es un motor eléctrico CC sin escobillas que divide una rotación completa en varios pasos iguales. Rota una distancia incremental específica por cada paso. El número de pasos que se ejecutan controla el grado de rotación del eje del motor.
Los motores de paso tienen cierta capacidad inherente para controlar la posición, ya que tienen pasos de salida integrados. Pueden controlar con gran precisión cuán lejos y cuán rápido rotará el motor de paso. El número de pasos que ejecuta el motor es igual al número de comandos de pulsos del controlador. Un motor de paso rotará una distancia y a una velocidad proporcional al número de la frecuencia de sus comandos de pulso.

Answer: A it is true.
Explanation: It is true under Subpart C—Information Security Responsibilities for Employees who Manage or Use Federal Information Systems
Number 3 and 4
(3) Program and functional managers must receive training in information security basics; management and implementation level training in security planning and system/application security management; and management and implementation level training in system/application life cycle management, risk management, and contingency planning.
(4) Chief Information Officers (CIOs), IT security program managers, auditors, and other security-oriented personnel (e.g., system and network administrators, and system/application security officers) must receive training in information security basics and broad training in security planning, system and application security management, system/application life cycle management, risk management, and contingency planning.
Answer:
The interpretation including its given question has always been discussed in the following sections on the elaboration.
Explanation:
In engineering, a function or a feature has always been perceived as a particular process, active engagement, or workload a system must perform.
- Generally differentiated consequently throughout the life span of infrastructure projects: Specifications as well as Functional technical specifications.
- Typically the Specifications define the most critical device attributes demanded.
Answer:
output=
Explanation:
output =transfer function ×input
here transfer function G=
input = unit impulse
in S domain unit impulse =1
so output =
=
