The rigid beam gh is supported by two cylinder members (ab and ef). a third cylinder (cd) is positioned directly between ab and ef. a gap of 0.04 mm exists between the bottom of gh and the top of cd. when a distributed load of 150 kn/m is applied to member gh, determine the internal compressive loads in the three cylinders. diameters of ab, cd, and ef

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

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
