You stand on the pedal of a bicycle. If you have a mass of (65 kg), the pedal makes an angle of (35°) above the horizontal, and the pedal is (18 cm) from the center of the chain ring, how much torque would you exert? τ = rFsin(θ) 114.8 N. m 6583.3 N. m 65.8 N. m 6.8 N. m

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

+15-35=-20

going in opposite directions
