A uniform beam of length L and mass mB is supported by two pillars located L/3 from either end, as shown in the figure. A duck of mass mD stands on one end. A scale is placed under each pillar. The entire system is in equilibrium.

a) Draw a free body diagram.

b) Enter an expression, in terms of defined quantities and g, for the force (FR) that the scale under the right pillar shows.

c) Enter an expression, in terms of defined quantities and g, for the force (FL) that the scale under the left pillar shows.

d) Enter an expression, in terms of defined quantities and g, for the sum or the scale readings.

the word that best describes martin luther king jr.'s tone in the video is dignified

martin luther king, jr. was a social activist and baptist minister who played a key role in the american civil rights movement from the mid-1950s until his assassination in 1968. the video shows his manner and attitude having or showing a composed or serious manner that is worthy of respect so dignified is the correct answer

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.
