Two blocks with masses m = 2 kg and m = 3 kg hang on either
Two blocks of masses1kgand2kgare connected by a metal wire goijng over a smooth pulley as shown in figure. The breaking stress of the metal is(40/3π)×106N/m2. Ifg=10ms−12, then what should be the minimum radlus of the wire used if it is not to break?
Two blocks(of massesmAandmB)are connected by a massless string that passes over a pulley, as shown below. The coefficient of kinetic friction betweenmAand the inclined plane(at angleθabove the horizontal)isμk.When the system is...
Moreover, the diagonal blocks with elliptic subtopologies are denoted by the corresponding propagator labels of the top sector. It is important to note that, with the exception of the top sector (kite), the two elliptic curves are completely decoupled from one another. We now proceed with the...
Two inertial masses (15, 16) have a radius of curvature almost equal to that of a skirt (14). Both have slots (33, 38) in which antifriction parallel sides blocks (40, 46) are mounted to turn on axes (41, 47). When the first plate is driven the masses are driven by the blocks...
In this context, two-dimensional π-conjugated covalent organic frameworks (2D c-COFs)15–18 represent a unique class of layer-stacked, crystalline 2DCPs with in-plane π-conjugation, which allow control over the spatial arrangement of molecular building blocks7,19. Despite the growing interest ...
6 B). Mutation of the +1/+19 element (M1) reduced gastrin responsiveness by 80%, whereas mutation of the +11/+27 element (M2) also reduced gastrin responsiveness by 80%. Mutations of both elements (M1 and M2) completely eliminated gastrin responsiveness by the +1/+27 construct (Fig. ...
In the discontinuum method, the material is directly idealized as an assembly of separate units, such as blocks or particles, bonded together at their contact points, and the internal damage is represented by the breakage of the bonds [6]. In addition, rock is a typically discontinuous and ...
(June–August, JJA), the ITCZ, as well as the SPH are shifted northward, and the central Andes experience their main dry season. The SPH causes large scale subsidence, which inhibits deep convection. Additionally, a strong westerly flow in the upper atmosphere blocks the transport of ...
(If it depends on the actual values of m1 and m2, put 'no'.) (c)Is there a net (non-zero) torque? (d)Given particular values of m1, m2, and L1, is it always possible to choose L2 (with L2 > L1) such that the masses have no angular acceleration? The Attempt at a ...
