Noah is attempting a mechanics problem in which three coplanar forces , , and are acting on a body. He needs to determine whether the body is in equilibrium or not. He remembers his teacher saying something about checking whether he could arrange the forces into a triangle. So, he draws the shown figure.
Noah concludes that the three forces are in equilibrium. Is he correct?
Which of the following best describes what he has done?
Three coplanar forces , , and are acting on a body in equilibrium. Their triangle of forces forms a right triangle as shown.
Given that and , find the magnitude of .
A body weighing 6.4 N is suspended by two strings and of lengths 2.1 cm and 2.8 cm, respectively. Given that the two strings are fixed from the top on the same horizontal line and perpendicular to each other, find the tensions in the two strings and .
