Answer:
Mechanical Advantage Formula
The efficiency of a machine is equal to the ratio of its output to its input. It is also equal to the ratio of the actual and theoretical MAs. But, it does not mean that low-efficiency machines are of limited use. An automobile jack, for example, have to overcome a great deal of friction and therefore it has low efficiency. But still, it is extremely valuable because small effort can be applied to lift a great weight.
Also, in another way the mechanical advantage is the force generated by a machine to the force applied to it which is applied in assessing the performance of the machine.
The mechanical advantage formula is:
MA = FBFA
Explanation:
MAmechanical advantageFBthe force of the object
FAthe effort to overcome the force
Answer:
Cylindrical
Explanation:
<em>A cylindrical grinder </em><em>is a tool for shaping the exterior of an item. Although cylindrical grinders may produce a wide range of forms, the item must have a central axis of rotation. Shapes such as cylinders, ellipses, cams, and crankshafts are examples of this.</em><em> Cylindrical grinding</em><em> machines are specialized grinding machines that are used to process cylinders, rods, and similar workpieces. The cylinders revolve in one direction between two centers, while the grinding wheel or wheels are close together and rotate in the other direction.</em>
Answer:
Stat PVC = Stat(82+98.5)
Stat PVT = Stat(59+71.5)
Explanation
PVI = 71 + 35
Let G1 = Grade 1; G2 = Grade 2
G1 = +2.1% ; G2 = -3.4%
Highest point of curve at station = 74 + 10
General equation of a curve:
At highest point of the curve 
Station PVT
Usando la ecuación de regresión que modela la frecuencia cardíaca máxima, podemos obtener el valor predicho de los problemas dados así:
La ecuación lineal que modela la frecuencia cardíaca máxima permitida en función de la edad del paciente está relacionada con la fórmula:
<em>x = edad del paciente; m = máx. frecuencia cardíaca permitida</em>
1.) <u>Frecuencia cardíaca máxima permitida para una persona de 50 años:</u>
Sustituye x = 50 en la ecuación:
m = -0,875 (50) + 190
m = 146,25
Por lo tanto, la frecuencia cardíaca máxima permitida es de aproximadamente 146 latidos / min.
2.) <u>Edad para una persona con frecuencia cardíaca máxima de 160 latidos / min</u>:
Sustituye m = 160 en la ecuación:
160 = -0,875x + 190
0,875x = 190 - 160
0,875x = 30
x = 30 / 0,875
x = 34,28
Por tanto, la edad de la persona sería de unos 34 años.
