  text: In the living cell, we encounter a large variety of motile processes such
    as organelle transport and cytoskeleton remodeling. These processes are driven
    by motor proteins that generate force by transducing chemical free energy into
    mechanical work. In many cases, the molecular motors work in teams to collectively
    generate larger forces. Recent optical trapping experiments on small teams of
    cytoskeletal motors indicated that the collectively generated force increases
    with the size of the motor team but that this increase depends on the motor type
    and on whether the motors are studied in vitro or in vivo. Here, we use the theory
    of stochastic processes to describe the motion of N motors in a stationary optical
    trap and to compute the N-dependence of the collectively generated forces. We
    consider six distinct motor types, two kinesins, two dyneins, and two myosins.
    We show that the force increases always linearly with N but with a prefactor that
    depends on the performance of the single motor. Surprisingly, this prefactor increases
    for weaker motors with a lower stall force. This counter-intuitive behavior reflects
    the increased probability with which stronger motors detach from the filament
    during strain generation. Our theoretical results are in quantitative agreement
    with experimental data on small teams of kinesin-1 motors.
