Mechanical Comprehension Practice Exam Questions

Mechanical Comprehension questions to prep for the ASVAB test

 

A bus traveling at an average rate of 50 kilometers per hour made the trip to town in 6 hours. If it had traveled at 45 kilometers per hour, how many more minutes would it have taken to make the trip?  40 MINUTES LONGER.          15 MINUTES LONGER.    44 MINUTES LONGER.    23 MINUTES LONGER.               "distance = rate × time or d = r × t

6 2/3 – 6 = 2/3 hours = 40 min

"             Mechanical Comprehension

A bus and a car leave the same place and traveled in opposite directions. If the bus is traveling at 50 mph and the car is traveling at 55 mph, in how many hours will they be 210 miles apart?       2 HRS.   1 HR. AND 50 MIN               3 HRS.   4 HRS. AND 30 MIN          "distance = rate × time or d = r × t

t=210/105 =2 hours

"             Mechanical Comprehension

Tom took a drive to town at an average rate of 40 mph. In the evening, he drove back at 30 mph. If he spent a total of 7 hours traveling, what is the distance traveled by John?     240 MILES           240 KILOMETERS       24 MILES             24 KILOMETERS"40t = 30(7 – t)

Use distributive property

40t = 210 – 30t

Isolate variable t

40t + 30t = 210

70t = 210

T=210/70 = 3

The next step: The distance traveled by Tom to town is

40t = 120

The distance traveled by Tom to go back is also 120

So, the total distance traveled by Tom is 240

The distance traveled by Tom is 240 miles.

Where is the center of mass located on a man?    CAN CHANGE IF PERSON MOVESIS LOCATED ABOVE THE WAIST          IS LOCATED ON THE OUTSIDE OF THE PERSON      IS LOCATED BELOW THE WAIST   A person's center of gravity is always changing when the person moves.         Mechanical Comprehension

Where is the center of mass located on a woman?              CAN CHANGE IF PERSON MOVESIS LOCATED ABOVE THE WAIST           IS LOCATED ON THE OUTSIDE OF THE PERSON      IS LOCATED BELOW THE WAIST   A person's center of gravity is always changing when the person moves.     Mechanical Comprehension

Where is the center of mass located on a child?    CAN CHANGE IF PERSON MOVESIS LOCATED ABOVE THE WAIST          IS LOCATED ON THE OUTSIDE OF THE PERSON      IS LOCATED BELOW THE WAIST   A person's center of gravity is always changing when the person moves.         Mechanical Comprehension

After a soccer ball has been kicked, what part of the ball follows a parabolic path?THE CENTER OF MASS     THE CENTER OF THE BALL, NOT INCLUDING THE COVER   NONE OF IT        ALL OF IT             The center of mass follows the parabolic path and nothing else.            Mechanical Comprehension

After a basketball is shot, what part of the ball follows a parabolic path?    THE CENTER OF MASS               THE CENTER OF THE BALL, NOT INCLUDING THE COVER   NONE OF IT        ALL OF IT             The center of mass follows the parabolic path and nothing else.            Mechanical Comprehension

After a baseball has been thrown, what part of the ball follows a parabolic path?    THE CENTER OF MASS     THE CENTER OF THE BALL, NOT INCLUDING THE COVER   NONE OF IT        ALL OF IT             The center of mass follows the parabolic path and nothing else.            Mechanical Comprehension

Newton had how many laws of motion?  3             1             0             5             Newton changed how scientist understood our universe. Newton’s three laws of motion are 1) Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. 2) The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors, in this law the direction of the force vector is the same as the direction of the acceleration vector. 3) For every action there is an equal and opposite reaction.               Mechanical Comprehension

According to Newton’s third law of motion, for every action there is a(n) _________________.                EQUAL AND OPPOSITE REACTION              UNEQUAL REACTION      UNKNOWN REACTION    AN UNEQUAL AND OPPOSITE REACTION        Newton changed how scientist understood our universe. Newton’s three laws of motion are 1) Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. 2) The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma.

    This story reminded me of how I finally passed the ASVAB after failing it twice.

    What really helped me was to do lots of online practice, learn to eliminate wrong answers, and get comfortable with the time limits.

    Before I learned how to pass the ASVAB, I wasted a lot of time looking for free sample questions and study materials that didn't help me at all.

    The secret is to use the right materials and practice under the same pressure as in the real test.

    The website that helped me the most to pass the ASVAB is this one:
