1. Torque is is a force acting around a pivotal point that causes rotation.
Torque= force*radius*sinθ

2. The axis determines the magnitude of the torque as a force applied further has more torque than a force applied closer to the axis.

3. The 1st Law of Conservation of Energy- energy cannot be created or destroyed or created
The 2nd law- entropy of isolated systems is always increasing
The 3rd law- as the temperature of a system reaches absolute zero the entropy approaches a constant value

Problem Set 1:
1. (45cm - 0cm)= 45cm = 0.45m
0.45m * 2N * sin(90) = -0.9N m
*clockwise torque is negative
2. (45cm - 10cm)= 35cm = 0.35m
0.35m * -5N * sin(270) = 1.75N m
*counter clockwise torque is positive
3. (45cm - 35cm)= 10cm = 0.10m
0.10m * -4N * sin(270) = 0.4N m
4. (80cm - 45cm)= 35cm = 0.35m
0.35m * x * sin(270) = -0.35x N m
x = -3.6N   so -0.35 * -3.6 = 1.26N m which is positive because the force is applied in a clockwise direction

Problem Set 2:
B:    A= -3N so
-3N * 0.1m = B * 0.12m
B= -2.5N
C:  A+B= -5.5N so
-5.5N * 0.25m = C * 0.15m
C= -9.2N
D:  A+B+C= -14.7N so
-14.7N * 0.35m = (E+D) * 0.25m
E+D = -20.6 N
(-20.6N - E) * 0.1m = (-20.6 - D) * 0.1m
D= -10.3N
E= -10.3N
F: A+B+C+D+E= -35.3N
-35.3N * 0.25m = F * 0.45m
F= -19.6N

1. Torque is the unit that measures the amount of force acting on an object causing the object to rotate. The formula is t=F*r*sinθ.

2. The point of axis is important because because it determines the direction and angle the object must rotate.

3. There are three laws of thermodynamics. The first is the Law of Conservation of Energy which states that energy cannot be created or destroyed. The second law is the Law of Entropy, which states that the entropy of an isolated system always increases. The third law doesn’t really have a name, but it states that the entropy of a system approaches a constant value as the temperature approaches zero.

1. Torque is a force applied about an axis, fulcrum, or pivot and is defined as τ = F × r × sin θ where F = force, r = the distance from the axis to the point where the force is applied, and θ is the angle between F and r.
2. Torque acts about the axis, so distance from the axis and the angle between the force and the axis determine the magnitude of the torque. (A force that is applied far from the axis and perpendicular to it will have a large torque.)
3. The first law of thermodynamics states that the energy of an isolated system is constant. The second law of thermodynamics states that the total entropy of an isolated system always increases over time and the third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.
