Efficency = 28%

Explanation:

We have the load has a weight of:

$w =m*g\\w =12*9.81\\w = 117.72 [N]$

Work in physics is defined as the product of force (weight) by distance.

W=w*d

where:

W = work [J]

w = weight = 117.72[N]

d = distance = 5 [m]

$W=117.72*5\\W=588.6[J]$

Now power is defined as the relationship of work at a certain time.

$P=W/t\\$

where:

P = power [W]

W = work = 588.6[J]

t = time = 30[s]

$P=588.6/30\\P=19.62[W]$

Now the efficiency of a machine is defined as the power output over the power input to the machine. The power input should always be greater than the power output.

$efficency = \frac{Power_{out}}{Power_{in}}\\Efficeny = \frac{19.62}{70} \\Efficency = 0.28\\Efficency = 28%$
