The length of a bicycle pedal arm is 0.177 m, and a downward force of 145 N is applied to the pedal by the rider. What is the ma

kramer

Answer:

(a) 19.25 N-m

(b) 25.67 N-m

(c) 0 N-m

Explanation:

Given:

Length of the pedal arm (L) = 0.177 m

Downward force $(|\vec{F}|)$ = 145 N

Magnitude of torque is given by the formula:

$T=FL\sin\theta$

Where, $\theta\to angle\ between\ F\ and\ L$

(a)

Given:

$\theta=48.6$ °

Therefore, torque is given as:

$T=FL\sin\theta\\\\T=(145\ N)(0.177\ m)(\sin(48.6))\\\\T=19.25\ Nm$

Therefore, the torque is 19.25 N-m.

(b)

Given:

$\theta=90$ °

Therefore, torque is given as:

$T=FL\sin\theta\\\\T=(145\ N)(0.177\ m)(\sin(90))\\\\T=25.67\ Nm$

Therefore, the torque is 25.67 N-m.

(c)

Given:

$\theta=180$ °

Therefore, torque is given as:

$T=FL\sin\theta\\\\T=(145\ N)(0.177\ m)(\sin(180))\\\\T=0\ Nm$

Therefore, the torque is 0 N-m.

A baseball is hit with a vertical speed of 10m/s and a horizontal speed of 30m/s.how long will the ball remain in the air

Phantasy [73]

First find the direction velocity
Vo = $\sqrt{Vx^2 + Vy^2} = \sqrt{30^2 + 10^2} = \sqrt{1000}$
tan θ = vy/vx = 10/30 = 1/3
so, sin θ = 1/√10 = √10/10

and time to reach further point is same with how long the ball in the air

$t = \frac{2vo . sin \alpha }{g} = \frac{2. \sqrt{1000} . 1/ \sqrt{10} }{10}$
$= \frac{2 . \sqrt{100} }{10} = \frac{2 . 10}{10} = 2 second$

The impedance of an inductor zind is determined to be 147 ohms at 2000 hz and its dc resistance rl is 25 ohms. what would be the

Margaret [11]

<span>The formula for inductance X is X=2*pi*freq*L. With the given information, we solve for L. The equation becomes: L = X/(2*pi*freq). Substituting the known variables gives us L = 147ohms / (2*pi*2000hz). Solving for L, L equals .0117. The inductance of this inductor is 11.7 mH.</span>

matrenka [14]

Answer:

a) 6.1 m

b) 4.6 s

c) 1.326 m/s

d) 0.325 m

Explanation:

a) The wave length is the distance between 2 crests λ = 6.1m

b) The period of the wave is the time it takes from the lowest point to the next lowest point, which is twice the time it takes from the lowest point to the highest point = 2*2.3 = 4.6 s

c) The speed of the wave is the distance per unit of time, or wave length over period = 6.1 / 4.6 = 1.326 m/s

d)The amplitude A is half the distance from the highest point to the lowest point = 0.65 / 2 = 0.325 m
