At one position during its cycle, the foot pushes straight down with a 430-N force on a bicycle pedal arm that is rotated an angle ϕ=55∘ from the vertical, as shown in (Figure 1). Figure1 of 1

Part A
If the force is applied r=0.18m from the axis of rotation, what magnitude of torque is produced?

When does your body conduct current more readily?

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

What is the angular momentum of the bar about the axle?
