Chapter 8.7, Problem 26E

(a)

To determine

To Find: The pull of the rope.

Answer to Problem 26E

The pull of the rope is $1101.34\text{N}$ .

Explanation of Solution

Given:

The mass of the ice is 300 kilograms is held on the ice slide by a rope parallel to the slide.

The slide is inclined at an angle of $22°$ .

Calculation:

The sketch for the given case is shown in Figure 1

Figure 1

Consider the pull on the rope is given by,

  $\begin{array}{c}mg\sin \theta =300\left(9.8\right)\sin 22\\ =1101.34\text{N}\end{array}$

(b)

To determine

To Find: Theforce of the slide.

Answer to Problem 26E

The force of the slide is $2725.92\text{N}$ .

Explanation of Solution

Consider the force on the slide is obtained as,

  $\begin{array}{c}mg\cos \theta =300\left(9.8\right)\cos 22\\ =2725.92\text{N}\end{array}$

Thus, the force of the slide is $2725.92\text{N}$ .
