Explanation Given data: Refer to the Figure P8.4 in the textbook for the walking of a man on the beam. Mass of the man ( m M ) is 70 kg. Mass of the beam ( m B ) is 10 kg. Formula used: Write the expression for static equilibrium condition of the force as follows. ∑ F = 0 (1) Here, ∑ F is the sum of the forces acting on any object. Write the expression for weight of the object as follows. w = m g (2) Here, m is the mass of the object, and g is the acceleration due to gravity, which is 9.8 m s 2 . Explanation: From the given data, it is clear that, the left support does not exert any upward force on the beam when the beam just starts to tip. From equation (1), the sum of the forces acts on the beam when it just starts to tip is zero. The following are the forces act on the beam when it just starts to tip. The force exerted by the right support in the upward direction, and The combined weight of the person and the beam in the downward direction. Modify the expression in equation (1) for the forces when the beam just starts to tip as follows. F right + [ − ( w M + w B ) ] = 0 (3) Here, F right is the forces exerted by the right support in the upward direction, w M is the weight of the man, and w B is the weight of the beam. Calculation of weight of the man: Substitute 70 kg for m , and 9.8 m s 2 for g in equation (2), w M = ( 70 kg ) ( 9

Center of Gravity of a system

The centre of gravity is a property that is based on the geometry of a rigid body or any particle. It is described as an equilibrium point or a hypothetical location where the total weight of the body is concentrated.

Certain types of particle detectors can be used to reconstruct the tracks left by unstable, fast-moving sub-atomic particles. Assume that a track with a length of L=2.97 mm in the laboratory frame of reference has been observed. Further assume that you determined from other detector data that the particle moved at a speed of L=0.910 ⚫ c, also in the laboratory frame of reference. c denotes the speed of light in vacuum. What proper lifetime would you determine for this particle from the data given? T= 4.0 S

While cruising down University Boulevard you are stopped by a cop who states that you ran a red traffic light. Because you don't want to pay the stiff fine, you are attempting a physics defense. You claim that due to the relativistic Doppler effect, the red color of the light λ=616 nm appeared green '=531 nm to you. The cop makes a quick calculation of his own and rejects your defense. How fast, in terms of your speed u divided by the speed of light in vacuum c, would you have to drive to justify your claim? Note that the speed u is taken to be a positive quantity. U 4.0 C
