complete solution 2025
24 - correct answer ✔What is the voltage drop of a 3 ohm resistor if a current
flowing through it is 8 A in Volts?
833.3 - correct answer ✔Determine the current in mA, if the voltage drop
through a 6 ohm resister is 5 V.(Use 4 sig fig)
kg*m^2/s^3 - correct answer ✔What is the MKS unit for Power in terms of
m,kg,s?(Do not use spaces or parentheses, use * for multiplication, use / for
division, and ^ for raising)
153 - correct answer ✔The box on a table saw indicates that the amperage
at startup is 1 Amps. Determine the resistance in ohms of the motor during
this time. (Hint: The average household voltage in the US is 153V?)
180 - correct answer ✔A student with a mass of 6 kg runs up three flights of
stairs in 1 s. The student has gone a vertical distance of 3 m. Determine the
amount of power the student generated to elevate his body to this height in
Watts.
8.5 - correct answer ✔Two parallel resistors each 5 ohm are connected to a
6 ohm in series, what is the equivalent resistance in ohms? (Use 4 sig figs)
3.692 - correct answer ✔How high can a block be vertically raised if the work
done is 48 J with an applied force of 13 N?
Torsion - correct answer ✔In addition to supporting tension or compression,
a beam can resist shear, bending, and
,P1*L - correct answer ✔Compute the magnitude of the moment on the left
side of fixed end of the beam. (no spaces in answer, use * for multiplication, /
for division ). Please enter P1 for the force. Do not use parentheses.
7.56 - correct answer ✔The vector forces (2.38N,-0.61N,2.98N) and (-
4.19N,0.07N,4.34N) are applied to the same point. What is the net magnitude
of force applied to the point in Newtons? (Use 4 sig figs.)
28.99 - correct answer ✔How much mass can a 1,109 Nm torque motor lift
using a 7.65 m diameter winch in kg? (Use 10 m/s^2 for gravity) (Use 4 sig
figs.)
negative - correct answer ✔What is the sign (or sense or direction) of the
moment that is created about point A by the force at C?
positive - correct answer ✔What sign (or sense or direction) of the moment is
required for the reaction at A for static equilibrium?
1/x - correct answer ✔Find the derivative of f(x) = ln x.
Strategy - correct answer ✔_____________________ is a plan or tactics to
obtain the goal but there may be many different types of machines that could
be used.
True - correct answer ✔A strategy is a basic approach to solving a problem,
yet there are still many different actual machines that could be constructed to
execute the strategy:
, False - correct answer ✔The "Pulley system" may be a functional
requirement of a strategy.
False - correct answer ✔It is common to analyze the bolt dimensions while
working on a strategy.
Create an accurate model, or stress calculations - correct answer ✔Which
statement below does not indicate which type of analysis for a strategy.
True - correct answer ✔The "Vertical Translation" may be a functional
requirement of strategy.
What - correct answer ✔According to the Deterministic Design Paradigm,
what question should the Strategy phase answer?
Motion - correct answer ✔A strategy is an idea initially described in the
simplest of forms that can specify types of _______________, but not how
they are achieved
True - correct answer ✔A "Pulley System" may be a Design Parameter of a
strategy.
False - correct answer ✔"Grippers" may be a functional requirement of a
strategy.
True - correct answer ✔The "Lead Screw" may be a functional requirement
of a concept.
