the table shows the dimensions of four wedges. which wedge requires the least amount of force to do a job? dimensions of four wedges thickness at widest part (in.) slope (in.) w 2 5 x 4 8 y 3 9 z 5 10 o w o x o y o z
Answer
Explanation:
Step1: Recall the principle
The mechanical advantage of a wedge is given by the ratio of the length of its slope to its thickness at the widest part. A higher mechanical - advantage means less force is required to do the job.
Step2: Calculate the mechanical advantage for each wedge
For wedge W: $\frac{5}{2}=2.5$ For wedge X: $\frac{8}{4}=2$ For wedge Y: $\frac{9}{3}=3$ For wedge Z: $\frac{10}{5}=2$
Step3: Compare the mechanical advantages
The highest mechanical advantage is for wedge Y with a value of 3.
Answer:
Y
