The tower crane is used to hoist the 2 Mg load upward at constant velocity. The 1.5 Mg jib BD, 0.5 Mg jib BC, and 6 Mg counterweight C have centers of mass at G1, G2, and G3, respectively. Determine the resultant moment produced by the load and the weights of the tower crane jibs about point A and point B.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

number of electrons for neutral cl

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
