Three coplanar equilibrium forces \( P = 40\text{ N} \), \( Q = x\text{ N} \) and \( R = y\text{ N} \) are acting on a body and the body is said to be in equilibrium when the angle included between each other is \( 120^\circ \), then \( x = \)

Which of the following key fits in the keyway of the hub only (i.e., there is no keyway on the shaft)?
In involute gear terminology, the difference between the tooth space and tooth thickness measured along the pitch circle, is known as:
In case of flat belt open drive, if the centre distance between pulleys is 2 m and both pulleys are equal in diameter of 1 m; then the length of the belt in meters is:
A solid shaft of diameter D carries a twisting moment that develops a maximum shear stress $\tau$. If the solid shaft is replaced by a hollow shaft having outside diameter D and inside diameter D/2; then the maximum shear stress in the hollow shaft will be:
A simply supported beam having length = L, width = B and depth = H, carries a concentrated load W at its centre and undergoes a deflection $\delta$ under the load. If the width and depth are interchanged, the deflection at the centre of the beam would attain a value:
