Using the equations of equilibrium, determine the horizontal reaction at point D. (Hint: Write equation for sum of moments about point A = 0, including the reactions at D in the equation. Solve the equation directly for Dx.)

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

i think the answer is a and b

i wish you luck
