Q1
How much longer does a 16.1m long steel girder in a house get if
the temperature changes from 15C to +36C. (steel = 1.1 10
/C.)

5
Answer : cm
Question2
A car is parked in the sun. The windshield is 66cm by 170cm. How
much does the area of the
The figure shows the view from above a 17.6 kg tyre that is to be pulled by three
horizontal ropes. One rope's force (F1 = 50.0 N) is indicated. The forces from the
other ropes are to be arranged such that the tire's acceleration magnitude a is
minimised.
ParallelAxis Theorem

In the previous examples, the axis
of rotation coincided with the axis
of symmetry of the object
For an arbitrary axis, the parallelaxis theorem often simplifies
calculations
The theorem states I = ICM + MD 2

Q1
Can the sum of the magnitudes of two vectors ever be equal to the
magnitude of the sum of the same two vectors?
Multiple answers may be correct.
Select one or more:
a. No, because of the angle between the two vectors.
b. No, it is impossible for the ma
