Question

Пожалуйста помогите.Конец года,если не решу два в год!Момент силы,приложенной перпендикулярно плечу рычага длиной 20 см,равен 40 Н *м. Чему равна эта сила?

Answer 1

М-момент силы = 40Н
l  длина = 20 см= 0,2 м 
cos90=0
М=F*l*cos90. Так как cos90=0, то ответ будет равен 0

Answer 2

Calculating the Force Applied Perpendicular to the Lever Arm

To calculate the force applied perpendicular to the lever arm, we can use the formula:

Force (F) = Moment of Force (M) / Distance (d)

Given that the moment of force (M) is 40 N*m and the distance (d) is 20 cm, we can convert the distance to meters and then use the formula to find the force.

Converting 20 cm to meters: 20 cm = 0.20 meters

Now, we can use the formula to calculate the force: Force (F) = 40 N*m / 0.20 m

Force (F) = 200 N

So, the force applied perpendicular to the lever arm is 200 N. This is calculated using the formula for moment of force and the given values of moment of force and distance
