A light bar AD is suspended from a cable BE and supports a 20-kg block at C. The ends A and D of the bar are in contact with fri

babymother [125]

Answer:

Tension in cable BE= 196.2 N

Reactions A and D both are 73.575 N

Explanation:

The free body diagram is as attached sketch. At equilibrium, sum of forces along y axis will be 0 hence

$T_{BE}-W=0$ hence

$T_{BE}=W=20*9.81=196.2 N$

Therefore, tension in the cable, $T_{BE}=196.2 N$

Taking moments about point A, with clockwise moments as positive while anticlockwise moments as negative then

$196.2\times 0.125- 196.2\times 0.2+ D_x\times 0.2=0$

$24.525-39.24+0.2D_x=0$

$D_x=73.575 N$

Similarly,

$A_x-D_y=0$

$A_x=73.575 N$

Therefore, both reactions at A and D are 73.575 N

The answer is B because it could be feasible but it’s not a need it and you got a time frame but it’s not a requirement and it doesn’t have to be unique.

What is the measurement of this square?<br> A.075<br> B. 1.75<br> C. 0.34

Katena32 [7]

Answer:

0.75 in

Explanation:

The 1 inch measure has 16 divisions.

Find the measure of 1 division as: 1/16 = 0.0625 in

The side length of the square has 12 divisions

1 division = 0.0625 in

12 divisions = 0.0625*12 = 0.75 in

The correct answer choice is A. 0.75.

Answer choices B is incorrect because from the diagram, it is clear that the side length of this square is less that 1 inch.

Answer choice C is incorrect because 0.34 in will mean 0.34/0.0625 divisions. This is 5 divisions, yet the square side length covers 12 divisions.
