Question

As shown above an adhesive has been applied to contacting forces of two blocks so that the blocks interact with an adhesive force that has magnitude. Fadhesion • A tension, T, is exerted by a wire attached to the upper blocks causing the blocks to remain at rest. The two blocks have weights, Wbottom and Wtop. Which of the following must be true?

A) T = W bottom + W top + F adhesion

B) T= W top - F adhesion

C) W bottom = F adhesion

D) W top = T

Answer 1

the bottom block is not accelerating
therefore the adhesion force up on it is equal and opposite to its weight.
C

Answer 2
