The design with the highest mechanical advantage is option A: length 16in thickness 4in.
To calculate the mechanical advantage, we use the formula MA = Lt.
For option A, MA = 16 * 4 = 64.
For option B, MA = 5 * 5 = 25.
For option C, MA = 12 * 2 = 24.
For option D, MA = 6 * 2 = 12.
Therefore, option A has the highest mechanical advantage of all the given designs.
A wedge is a simple machine that is essentially two inclined planes. It is used to separate objects, such as in the head of an axe. The mechanical advantage of a wedge is given by MA = Lt , where L is the length of the wedge and t is the thickness. Which of these designs produces the highest mechanical advantage?(1 point) Responses
A length 16in thickness 4 in
B length 5in thickness 5in
C length 12 in thickness 2 in
D length 6 thickness 2in
