Question
Determine the force P that should be applied at the bottom of the ladder if a man that weighs 160 kN climbed up 4 m. from the top. The weight of the ladder is 40 kN and the angle of friction for the two contact surfaces is 15°. Answer in kN, rounded to the nearest hundredths. (type the value only, without the unit) 160 kN 4 8 12 W A
